The medium through which this Joy comes is next explained: "He that abideth in Me, the same bringeth forth much fruit." Fruit first, Joy next; the one the cause or medium of the other. Fruit-bearing is the necessary antecedent; Joy both the necessary consequent and the necessary accompaniment. It lay partly in the bearing fruit, partly in the fellowship which made that possible. Partly, that is to say, Joy lay in mere constant living in Christ's presence, with all that that implied of peace, of shelter, and of love; partly in the influence of that Life upon mind and character and will; and partly in the inspiration to live and work for others, with all that that brings of self-riddance and Joy in others' gain. All these, in different ways and at different times, are sources of pure Happiness. Even the simplest of them--to do good to other people--is an instant and infallible specific. There is no mystery about Happiness whatever. Put in the right ingredients and it must come out. He that abideth in Him will bring forth much fruit; and bringing forth much fruit is Happiness. The infallible receipt for Happiness, then, is to do good; and the infallible receipt for doing good is to abide in Christ. The surest proof that all this is a plain matter of Cause and Effect is that men may try every other conceivable way of finding Happiness, and they will fail. Only the right cause in each case can produce the right effect. Then the Christian experiences are our own making? In the same sense in which grapes are our own making, and no more. All fruits _grow_--whether they grow in the soil or in the soul; whether they are the fruits of the wild grape or of the True Vine. No man can _make_ things grow. He can _get them to grow_ by arranging all the circumstances and fulfilling all the conditions. But the growing is done by God. Causes and effects are eternal arrangements, set in the constitution of the world; fixed beyond man's ordering. What man can do is to place himself in the midst of a chain of sequences. Thus he can get things to grow: thus he himself can grow. But the grower is the Spirit of God.
