St. John viii. 17: If ye know these things, happy are ye if ye do them.

I ask you to think for a little while about the religion of Christ in its relation to happiness.

This is only one point in the circle of truth at the centre of which Jesus stands. But it is an important point because it marks one of the lines of power which radiate from Him. To look at it clearly and steadily is not to disregard other truths. The mariner takes the whole heavens of astronomy for granted while he shapes his course by a single star.

In the wish for happiness all men are strangely alike. In their explanations of it and in their ways of seeking it they are singularly different. Shall we think of this wish as right, or wrong; as a true star, or a will-o'-the-wisp? If it is right to wish to be happy, what are the conditions on which the fulfilment of this wish depends? These are the two questions with which I would come to Christ, seeking instruction and guidance.

I. The desire of happiness, beyond all doubt, is a natural desire. It is the law of life itself that every being seeks and strives toward the perfection of its kind, the realization of its own specific ideal in form and function, and a true harmony with its environment. Every drop of sap in the tree flows toward foliage and fruit. Every drop of blood in the bird beats toward flight and song. In a conscious being this movement toward perfection must take a conscious form. This conscious form is happiness,—the satisfaction of the vital impulse,—the rhythm of the inward life,—the melody of a heart that has found its keynote. To say that all men long for this is simply to confess that all men are human, and that their thoughts and feelings are an essential part of their life. Virtue means a completed manhood. The joyful welfare of the soul belongs to the fulness of that ideal. Holiness is wholeness. In striving to realize the true aim of our being, we find the wish for happiness implanted in the very heart of our effort.

Now what does Christ say in regard to this natural human wish? Does He say that it is an illusion? Does He condemn and deny it? Would He have accepted Goethe's definition: "religion is renunciation"?

Surely such a notion is far from the spirit of Jesus. There is nothing of the hardness of Stoicism, the coldness of Buddhism, in Christ's gospel. It is humane, sympathetic, consoling. Unrest and weariness, the fever of passion and the chill of despair, soul-solitude and heart-trouble, are the very things that He comes to cure. He begins His great discourse with a series of beatitudes. "Blessed" is the word. "Happy" is the meaning. Nine times He rings the changes on that word, like a silver bell sounding from His fair temple on the mountain-side, calling all who long for happiness to come to Him and find rest for their souls.

Christ never asks us to give up merely for the sake of giving up, but always in order to win something better. He comes not to destroy, but to fulfil,—to fill full,—to replenish life with true, inward, lasting riches. His gospel is a message of satisfaction, of attainment, of felicity. Its voice is not a sigh, but a song. Its final word is a benediction, a good-saying. "These things have I spoken unto you, that my joy might remain in you, and that your joy might be full."

If we accept His teaching we must believe that men are not wrong in wishing for happiness, but wrong in their way of seeking it. Earthly happiness,—pleasure that belongs to the senses and perishes with them,—earthly happiness is a dream and a delusion. But happiness on earth,—spiritual joy and peace, blossoming here, fruiting hereafter,—immortal happiness, is the keynote of life in Christ.

And if we come to Him, He tells us four great secrets in regard to it.

i. It is inward, and, not outward; and so it does not depend on what we have, but on what we are.

ii. It cannot be found by direct seeking, but by setting our faces toward the things from which it flows; and so we must climb the mount if we would see the vision, we must tune the instrument if we would hear the music.

iii. It is not solitary, but social; and so we can never have it without sharing it with others.

iv. It is the result of God's will for us, and not of our will for ourselves; and so we can only find it by giving our lives up, in submission and obedience, to the control of God.

For this is peace,—to lose the lonely note Of self in love's celestial ordered strain: And this is joy,—to find one's self again In Him whose harmonies forever float Through all the spheres of song, below, above,— For God is music, even as God is love.

This is the divine doctrine of happiness as Christ taught it by His life and with His lips. If we want to put it into a single phrase, I know not where we shall find a more perfect utterance than in the words which have been taught us in childhood,—words so strong, so noble, so cheerful, that they summon the heart of manhood like marching-music: "Man's chief end is to glorify God and enjoy Him forever."

Let us accept without reserve this teaching of our Divine Lord and Master in regard to the possibility and the duty of happiness. It is an essential element of His gospel. The atmosphere of the New Testament is not gloom, but gladness; not despondency, but hope. The man who is not glad to be a Christian is not the right kind of a Christian.

The first thing that commended the Church of Jesus to the weary and disheartened world in the early years of her triumph, was her power to make her children happy,—happy in the midst of afflictions, happy in the release from the burden of guilt, happy in the sense of Divine Fatherhood and human brotherhood, happy in Christ's victory over sin and death, happy in the assurance of an endless life. At midnight in the prison, Paul and Silas sang praises, and the prisoners heard them. The lateral force of joy,—that was the power of the Church.

"'Poor world,' she cried, 'so deep accurst, Thou runn'st from pole to pole To seek a draught to slake thy thirst,— Go seek it in thy soul.' *    *    *    *    * Tears washed the trouble from her face! She changed into a child! 'Mid weeds and wrecks she stood,—a place Of ruin,—but she smiled!"

Much has the Church lost of that pristine and powerful joy. The furnace of civilization has withered and hardened her. She has become anxious and troubled about many things. She has sought earthly honours, earthly powers. Richer she is than ever before, and probably better organized, and perhaps more intelligent, more learned,—but not more happy. The one note that is most often missing in Christian life, in Christian service, is the note of spontaneous joy.

Christians are not as much calmer, steadier, stronger, and more cheerful than other people as they ought to be. Some Christians are among the most depressing and worryful people in the world,—the most difficult to live with. And some, indeed, have adopted a theory of spiritual ethics which puts a special value upon unhappiness. The dark, morbid spirit which mistrusts every joyful feeling, and depreciates every cheerful virtue, and looks askance upon every happy life as if there must be something wrong about it, is a departure from the beauty of Christ's teaching to follow the dark-browed philosophy of the Orient.

The religion of Jesus tells us that cheerful piety is the best piety. There is something finer than to do right against inclination; and that is to have an inclination to do right. There is something nobler than reluctant obedience; and that is joyful obedience. The rank of virtue is not measured by its disagreeableness, but by its sweetness to the heart that loves it. The real test of character is joy. For what you rejoice in, that you love. And what you love, that you are like.

I confess frankly that I have no admiration for the phrase "disinterested benevolence," to describe the main-spring of Christian morals. I do not find it in the New Testament: neither the words, nor the thing. Interested benevolence is what I find there. To do good to others is to make life interesting and find peace for our own souls. To glorify God is to enjoy Him. That was the spirit of the first Christians. Was not St. Paul a happier man than Herod? Did not St. Peter have more joy of his life than Nero? It is said of the first disciples that they "did eat their meat with gladness and singleness of heart." Not till that pristine gladness of life returns will the Church regain her early charm for the souls of men. Every great revival of Christian power—like those which came in the times of St. Francis of Assisi and of John Wesley—has been marked and heralded by a revival of Christian joy.

If we want the Church to be mighty in power to win men, to be a source of light in the darkness, a fountain of life in the wilderness, we must remember and renew, in the spirit of Christ, the relation of religion to human happiness.

II. What, then, are the conditions upon which true happiness depends? Christ tells us in the text: If ye know these things, happy are ye if ye do them.

This is the blessing with a double if. "If ye know,"—this is the knowledge which Christ gives to faith. "If ye do,"—this is the obedience which faith gives to Christ. Knowing and Doing,—these are the twin pillars, Jachin and Boaz, on which the house of happiness is built. The harmony of faith and life,—this is the secret of inward joy and power.

You remember when these words were spoken. Christ had knelt to wash the disciples' feet. Peter, in penitence and self-reproach, had hesitated to permit this lowly service of Divine love. But Christ answered by revealing the meaning of His act as a symbol of the cleansing of the soul from sin. He reminded the disciples of what they knew by faith,—that He was their Saviour and their Lord. By deed and by word He called up before them the great spiritual truths which had given new meaning to their life. He summoned them to live according to their knowledge, to act upon the truth which they believed.

I am sure that His words sweep out beyond that quiet upper room, beyond that beautiful incident, to embrace the whole spiritual life. I am sure that He is revealing to us the secret of happy living which lies at the very heart of His gospel, when He says: If ye know these things, happy are ye if ye do them.

i. "If ye know,"—there is, then, a certain kind of knowledge without which we can not be happy. There are questions arising in human nature which demand an answer. If it is denied we can not help being disappointed, restless, and sad. This is the price we have to pay for being conscious, rational creatures. If we were mere plants or animals we might go on living through our appointed years in complete indifference to the origin and meaning of our existence. But within us, as human beings, there is something that cries out and rebels against such a blind life. Man is born to ask what things mean. He is possessed with the idea that there is a significance in the world beyond that which meets his senses.

John Fiske has brought out this fact very clearly in his last book, Through Nature to God. He shows that "in the morning twilight of existence the Human Soul vaguely reached forth toward something akin to itself, not in the realm of fleeting phenomena, but in the Eternal Presence beyond." He argues by the analogy of evolution, which always presupposes a real relation between the life and the environment to which it adjusts itself, that this forth-reaching and unfolding of the soul implies the everlasting reality of religion.

The argument is good. But the point which concerns us now is simply this. The forth-reaching, questioning soul can never be satisfied if it touches only a dead wall in the darkness, if its seeking meets with the reply, "You do not know, and you never can know, and you must not try to know." This is agnosticism. It is only another way of spelling unhappiness.

"Since Christianity is not true," wrote Ernest Renan, "nothing interests me, or appears worthy my attention." That is the logical result of losing the knowledge of spiritual things,—a life without real interest, without deep worth,—a life with a broken spring.

But suppose Renan is mistaken. Suppose Christianity is true. Then the first thing that makes it precious, is that it answers our questions, and tells us the things that we must know in order to be happy.

Christianity is a revealing religion, a teaching religion, a religion which conveys to the inquiring spirit certain great and positive solutions of the problems of life. It is not silent, nor ambiguous, nor incomprehensible in its utterance. It replies to our questions with a knowledge which, though limited, is definite and sufficient. It tells us that this "order of nature, which constitutes the world's experience, is only one portion of the total universe." That the ruler of both worlds, seen and unseen, is God, a Spirit, and the Father of our spirits. That He is not distant from us nor indifferent to us, but that He has given His eternal Son Jesus Christ to be our Saviour. That His Spirit is ever present with us to help us in our conflicts with evil, in our efforts toward goodness. That He is making all things work together for good to those that love Him. That through the sacrifice of Christ every one who will may obtain the forgiveness of sins and everlasting peace. That through the resurrection of Christ all who love Him and their fellow-men shall obtain the victory over death and live forever.

Now these are doctrines. And it is just because Christianity contains such doctrines that it satisfies the need of man.

"The first and the most essential condition of true happiness," writes Professor Carl Hilty, the eminent Swiss jurist, "is a firm faith in the moral order of the world. What is the happy life? It is a life of conscious harmony with this Divine order of the world, a sense, that is to say, of God's companionship. And wherein is the profoundest unhappiness? It is in the sense of remoteness from God, issuing into incurable restlessness of heart, and finally into incapacity to make one's life fruitful or effective."

What shall we say, then, of the proposal to adapt Christianity to the needs of the world to-day by eliminating or ignoring its characteristic doctrines? You might as well propose to fit a ship for service by taking out its compass and its charts and cutting off its rudder. Make Christianity silent in regard to these great questions of spiritual existence, and you destroy its power to satisfy the heart.

What would the life of Christ mean if these deep truths on which He rested and from which He drew His strength, were uncertain or illusory? It would be the most pathetic, mournful, heartbreaking of all phantoms.

What consoling, cheering power would be left in the words of Jesus if His doctrine were blotted out and His precept left to stand alone? Try the experiment, if it may be done without irreverence: read His familiar discourses in the shadow of agnosticism.

'Blessed are the poor in spirit, for theirs is a hopeless poverty. Blessed are the pure in heart, for they know not whether they shall see God. Blessed are ye when men shall revile you and persecute you, for ye have no promise of a heavenly reward.

'Enter into thy closet and when thou hast shut the door, keep silence, for thou canst not tell whether there is One to hear thy voice in secret. Take no thought for the morrow, for thou knowest not whether there is a Father who careth for thee.

'God is unknown, and they that worship Him must worship Him in ignorance and doubt. No man hath ascended up into heaven, neither hath any man come down from heaven, for the Son of Man hath never been in heaven. That which is born of the flesh is flesh, and that which is born of the spirit is a dream. Man shall not live by bread alone, neither shall he listen for any word from the mouth of God. I proceeded forth and came from darkness, I came of myself, I know not who sent me. My sheep hear my voice, and I know them, and they follow me, but I can not give unto them eternal life, for they shall perish and death shall pluck them out of my hand. Let not your heart be troubled; ye believe not in God, ye need not believe in me. Keep my commandments, and I will not pray for you, and ye shall abide without a Comforter. In the world ye shall have tribulation, but be of good cheer, for ye know not whether there is a world to come. I came forth from darkness into the world, and again I leave the world and return to darkness. Peace I leave with you. If ye loved me ye would rejoice because I said, I go into darkness, and where I am there shall ye be also.'

Is it conceivable that any suffering, sorrowing human soul should be comforted and strengthened by such a message as this? Could it possibly be called a gospel, glad tidings of great joy to all people?

And yet what has been omitted here from the words of Christ? Nothing but what men call doctrines: the personality of God, the divinity of Christ, the Atonement, the presence and power of the Holy Spirit, the sovereignty of the Heavenly Father, the truth of the divine revelation, the reality of the heavenly world, the assurance of immortal life. But it is just from these doctrines that the teaching of Jesus draws its peculiar power to comfort and inspire. They are the rays of light which disperse the gloom of uncertainty. They are the tones of celestial music which fill the heart of man with good cheer.

Let us never imagine that we can strengthen Christianity by leaving out the great doctrines which have given it life and power. Faith is not a mere matter of feeling. It is the acceptance of truth, positive, unchanging, revealed truth, in regard to God and the world, Christ and the soul, duty and immortality. The first appeal to faith lies in the clearness and vividness, the simplicity and joy, with which this truth is presented.

There has not been too much preaching of doctrine in this age. There has been too little. And what there has been, has been too dull and cold and formal, too vague and misty, too wavering and uncertain.

What the world wants and waits for to-day is a strong, true, vital preaching of doctrine. The Church must realize anew the precious value of the truths which Christ has given her. She must not conceal them or cast them away; she must bring them out into the light, press them home upon the minds and hearts of men. She must simplify her statement of them, so that men can understand what they mean. She must not be content with repeating them in the language of past centuries. She must translate them into the language of to-day. First century texts will never wear out because they are inspired. But seventeenth century sermons grow obsolete because they are not inspired. Texts from the Word of God, preaching in the words of living men,—that is what we need.

We must think about the doctrines of Christianity more earnestly and profoundly. We must renew our Christian evidences, as an army fits itself with new weapons. The old-fashioned form of the "argument from design in nature" has gone out with the old-fashioned books of science which it used. But there is a new and more wonderful proof of God's presence in the world,—the argument from moral ends in evolution. Every real advance of science makes the intelligent order of the universe more sublimely clear. Every century of human experience confirms the Divine claims and adds to the Divine triumphs of Jesus Christ. Social progress has followed to a hair's breadth the lines of His gospel; and He lays His hand to-day with heavenly wisdom on the social wants that still trouble us, "the social lies that warp us from the living truth." Christ's view of life and the world is as full of sweet reasonableness now as it was in the first century. Every moral step that man has taken upward has brought a wider, clearer vision of his need of such a religion as that which Christ teaches.

Let not the Church falter and blush for her doctrines. Let her not turn and go down the hill of knowledge to defend her position in the valley of ignorance. Let her go up the hill, welcoming every wider outlook, rejoicing in every new discovery, gathering fresh evidences of the truths which man must believe concerning God and new motives to the duties which God requires of man.

But in doing this we must put the emphasis of our preaching to-day where it belongs, where Christ puts it, on the doctrines that are most important to human life and happiness. We can afford to let the fine metaphysical distinctions of theology rest for a while, and throw all our force on the central, fundamental truths which give steadiness and courage and cheer to the heart of man. I will not admit that it makes no difference to a man of this age whether or not he believes in the personal God and the Divine Christ. If he really believes, it makes all the difference between spiritual strength and spiritual weakness, between optimism and pessimism. I will not admit that it makes no difference to a learned scholar or a simple labourer to-day whether he accepts or ignores the doctrine of the atonement, the doctrine of personal immortality. If he knows that Christ died for him, that there is a future beyond the grave, it makes all the difference between despair and hope, between misery and consolation, between the helpless frailty of a being that is puffed out like a candle, and the joyful power of an endless life.

My brethren, we must work and pray for a true revival of Christian doctrine in our age. We must deepen our own hold upon the truths which Christ has taught us. We must preach them more simply, more confidently, more reasonably, more earnestly. We must draw from them the happiness and the help, the comfort and the inspiration, that they have to give to the souls of men. But most of all, we must keep them in close and living touch with the problems of daily duty and experience. For no doctrine, however high, however true, can make men happy until it is translated into life.

ii. Here is the second if, on which the power of religion to confer happiness depends: If ye know, happy are ye if ye do these things.

Between the knowing and the doing there is a deep gulf. Into that abyss the happiness of many a man slips, and is lost. There is no peace, no real and lasting felicity for a human life until the gulf is closed, and the continent of conduct meets the continent of creed, edge to edge, lip to lip, firmly joined forever.

It is not a blessing to know the things that Christ teaches, and then go on living as if they were false or doubtful. It is a trouble, a torment, a secret misery. To know that God is our Father, and yet to withhold our love and service from Him; to know that Christ died for us, and yet to deny Him and refuse to follow Him; to know that there is an immortal life, and yet to waste and lose our souls in the pursuit of sensual pleasure and such small portion of the world as we may hope to gain,—surely that is the deepest of all unhappiness.

But the right kind of knowing carries in its heart the doing of the truth. And the right kind of doing leads to a fuller and happier knowing. "If any man will do God's will," declares Christ, "he shall know of the doctrine."

Let a man take the truth of the Divine Fatherhood and begin to conform his life to its meaning. Let him give up his anxious worryings, his murmurings, his complainings, and trust himself completely to his Father's care. Let him do his work from day to day as well as he can and leave the results to God. Let him come to his Father every day and confess his faults and ask for help and guidance. Let him try to obey and please God for love's sake. Let him take refuge from the trials and confusions and misunderstandings of the world, from the wrath of men and the strife of tongues, in the secret of his Father's presence. Surely if he learns the truth thus, by doing it, he will find happiness.

Or take the truth of immortality. Let a man live now in the light of the knowledge that he is to live forever. How it will deepen and strengthen the meaning of his existence, lift him above petty cares and ambitions, and make the things that are worth while precious to his heart! Let him really set his affections on the spiritual side of life, let him endure afflictions patiently because he knows that they are but for a moment, let him think more of the soul than of the body, let him do good to his fellow-men in order to make them sharers of his immortal hope, let him purify his love and friendship that they may be fit for the heavenly life. Surely the man who does these things will be happy. It will be with him as with Lazarus, in Robert Browning's poem, "The Epistle of Karshish." Others will look at him with wonder and say:

"Whence has the man the balm that brightens all? This grown man eyes the world now like a child."

Yes, my brethren, this is the sure result of following out the doctrines of Christ in action, of living the truths that He teaches,—a simple life, a childlike life, a happy life. And this also the Church needs to-day, as well as a true revival of doctrine.

A revival of simplicity, a revival of sincerity, a revival of work: this will restore unto us the joy of salvation. And with the joy of salvation will come a renewal and expansion of power.

The inconsistency of Christians is the stronghold of unbelief. The lack of vital joy in the Church is the chief cause of indifference in the world. The feeble energy, the faltering and reluctant spirit, the weariness in well-doing with which too many believers impoverish and sadden their own hearts, make other men question the reality and value of religion and turn away from it in cool neglect.

What, then, is the duty of the Church? What must she do to win the confidence of the world? What is the best way for her to "prove her doctrine all divine"?

First, she must increase her labours in the love of men: second, she must practice the simple life, deepening her trust in God.

Suppose that a fresh flood of energy, brave, cheerful, joyous energy, should be poured into all the forms of Christian work. Suppose that Foreign Missions and Home Missions should no longer have to plead and beg for support, but that plenty of money should come flowing in to send out every missionary that wants to go, and that plenty of the strongest and best young men should dedicate their lives to the ministry of Christ, and that every household where His gospel is believed should find its highest honour and its greatest joy in helping to extend His kingdom.

And then suppose that the Christian life, in its daily manifestation, should come to be marked and known by simplicity and happiness. Suppose that the followers of Jesus should really escape from bondage to the evil spirits of avarice and luxury which infect and torment so much of our complicated, tangled, artificial, modern life. Suppose that instead of increasing their wants and their desires, instead of loading themselves down on life's journey with so many bags and parcels and boxes of superfluous luggage and bric-a-brac that they are forced to sit down by the roadside and gasp for breath, instead of wearing themselves out in the dusty ways of ostentation and vain show or embittering their hearts because they can not succeed in getting into the weary race of wealth and fashion,—suppose instead of all this, they should turn to quiet ways, lowly pleasures, pure and simple joys, "plain living and high thinking." Suppose they should truly find and show their happiness in the knowledge that God loves them and Christ died for them and heaven is sure, and so set their hearts free to rejoice in life's common mercies, the light of the sun, the blue of the sky, the splendour of the sea, the peace of the everlasting hills, the song of birds, the sweetness of flowers, the wholesome savour of good food, the delights of action and motion, the refreshment of sleep, the charm of music, the blessings of human love and friendship,—rejoice in all these without fear or misgiving, because they come from God and because Christ has sanctified them all by His presence and touch.

Suppose, I say, that such a revival of the joy of living in Christ and working for Christ should silently sweep over the Church in the Twentieth Century. What would happen? Great would be the peace of her children. Greater still would be their power.

This is the message which I have to bring to you, my brethren, in this General Assembly of the Presbyterian Church. You may wonder that it is not more distinctive, more ecclesiastical, more specially adapted to the peculiarities of our own denomination. You may think that it is a message which could just as well be brought to any other Church on any other occasion. With all my heart I hope that is true. The things that I care for most in our Church are not those which divide us from other Christians but those which unite us to them. The things that I love most in Christianity are those which give it power to save and satisfy, to console and cheer, to inspire and bless human hearts and lives. The thing that I desire most for Presbyterianism is that it should prove its mission and extend its influence in the world by making men happy in the knowing and the doing of the things which Christ teaches.

The Church that the Twentieth Century will hear most gladly and honour most sincerely will have two marks. It will be the Church that teaches most clearly and strongly the truths that Jesus taught. It will be the Church that finds most happiness in living the simple life and doing good in the world.
