Perhaps it is not pressing the figure too hard to remark that the fruit differs from timber in this respect--that it enters into and nourishes the life of man. No doubt in this allegory fruit-bearing primarily and chiefly indicates that God's purpose in creating man is satisfied. The tree He has planted is not barren, but fruitful. But certainly a great distinction between the selfish and the unselfish man, between the man who has private ambitions and the man who labours for the public good, lies in this--that the selfish man seeks to erect a monument of some kind for himself, while the unselfish man spends himself in labours that are not conspicuous, but assist the life of his fellows. An oak carving or a structure of hard wood will last a thousand years and keep in memory the skill of the designer: fruit is eaten and disappears, but it passes into human life, and becomes part of the stream that flows on for ever. The ambitious man longs to execute a monumental work, and does not much regard whether it will be for the good of men or not; a great war will serve his turn, a great book, anything conspicuous. But he who is content to be a branch of the True Vine will not seek the admiration of men, but will strive to introduce a healthy spiritual life into those he can reach, even although in order to do so he must remain obscure and must see his labours absorbed without notice or recognition.
Does the teaching of this allegory, then, accord with the facts of life as we know them? Is it a truth, and a truth we must act upon, that apart from Christ we can do nothing? In what sense and to what extent is association with Christ really necessary to us?
Something may of course be made of life apart from Christ. A man may have much enjoyment and a man may do much good apart from Christ. He may be an inventor, who makes human life easier or safer or fuller of interest. He may be a literary man, who by his writings enlightens, exhilarates, and elevates mankind. He may, with entire ignorance or utter disregard of Christ, toil for his country or for his class or for his cause. But the best uses and ends of human life cannot be attained apart from Christ. Only in Him does the reunion of man with God seem attainable, and only in Him do God and God's aim and work in the world become intelligible. He is as necessary for the spiritual life of men as the sun is for this physical life. We may effect something by candle-light; we may be quite proud of electric light, and think we are getting far towards independence; but what man in his senses will be betrayed by these attainments into thinking we may dispense with the sun? Christ holds the key to all that is most permanent in human endeavour, to all that is deepest and best in human character. Only in Him can we take our place as partners with God in what He is really doing with this world. And only from Him can we draw courage, hopefulness, love to prosecute this work. In Him God does reveal Himself, and in Him the fulness of God is found by us. He is in point of fact the one moral stem apart from whom we are not bearing and cannot bear the fruit God desires.
If, then, we are not bringing forth fruit, it is because there is a flaw in our connection with Christ; if we are conscious that the results of our life and activity are not such results as He designs, and are in no sense traceable to Him, this is because there is something about our adherence to Him that is loose and needs rectification. Christ calls us to Him and makes us sharers in His work; and he who listens to this call and counts it enough to be a branch of this Vine and do His will is upheld by Christ's Spirit, is sweetened by His meekness and love, is purified by His holy and fearless rectitude, is transformed by the dominant will of this Person whom he has received deepest into his soul, and does therefore bring forth, in whatever place in life he holds, the same kind of fruit as Christ Himself would bring forth; it is indeed Christ who brings forth these fruits, Christ at a few steps removed--for every Christian learns, as well as Paul, to say, "Not I, but Christ in me." If, then, the will of Christ is not being fulfilled through us, if there is good that it belongs to us to do, but which remains undone, then the point of juncture with Christ is the point that needs looking to. It is not some unaccountable blight that makes us useless; it is not that we have got the wrong piece of the wall, a situation in which Christ Himself could bear no precious fruit. The Husbandman knew His own meaning when He trained us along that restricted line and nailed us down; He chose the place for us, knowing the quality of fruit He desires us to yield. The reason of our fruitlessness is the simple one, that we are not closely enough attached to Christ.
