Of course the metaphor that light, like a tree, grows and blossoms and puts forth fruit, is a very strong one. And its very violence and incongruity help its force. Fruit is generally used in Scripture in a good sense. It conveys the notion of something which is the natural outcome of a vital power, and so, when we talk about the light being fruitful, we are setting, in a striking image, the great Christian thought that, if you want to get right conduct, you must have renewed character; and that if you have renewed character you will get right conduct. This is the principle of my text. The light has in it a productive power; and the true way to adorn a life with all things beautiful, solemn, lovely, is to open the heart to the entrance of Jesus Christ.
God's way is--first, new life, then better conduct. Men's way is, cultivate morality, seek after purity, try to be good.' And surely conscience and experience alike tell us that that is a hopeless effort. To begin with what should be second is an anachronism in morals, and will be sure to result in failure in practice. He is not a wise man that tries to build a house from the chimneys downwards. And to talk about making a man's doings good before you have secured a radical change in the doer, by the infusion into him of the very life of Jesus Christ Himself, is to begin at the top story, instead of at the foundation. Many of us are trying to put the cart before the horse in that fashion. Many of us have made the attempt over and over again, and the attempt always has failed and always will fail. You may do much for the mending of your characters and for the incorporation in your lives of virtues and graces which do not grow there naturally and without effort. I do not want to cut the nerves of any man's strugglings, I do not want to darken the brightness of any man's aspirations, but I do say that the people who, apart from Jesus Christ, and the entrance into their souls by faith of His quickening power, are seeking, some of them nobly, some of them sadly, and all of them vainly, to cure their faults of character, will never attain anything but a superficial and fragmentary goodness, because they have begun at the wrong end.
But make the tree good,' and its fruit will be good. Get Christ into your heart, and all fair things will grow as the natural outcome of His indwelling. The fruitfulness of the light is not put upon its right basis until we come to understand that the light is Christ Himself, who, dwelling in our hearts by faith, is made in us as well as unto us wisdom, and righteousness, and salvation, and redemption.' The beam that is reflected from the mirror is the very beam that falls on the mirror, and the fair things in life and conduct which Christian people bring forth are in very deed the outcome of the vital power of Jesus Christ which has entered into them. I live, yet not I, but Christ liveth in me,' is the Apostle's declaration in the midst of his struggles; and the perfected saints before the throne cast their crowns at His feet, and say, Not unto us! not unto us, but unto Thy name be the glory.' The talent is the Lord's, only the spending of it is the servant's. And so the order of the Divine appointment is, first, the entrance of the light, and then the conduct that flows from it.
Note, too, how this same principle of the fruitfulness of the light gives instruction as to the true place of effort in the Christian life. The main effort ought to be to get more of the light into ourselves. Abide in Me, and I in you.' And so, and only so, will fruit come.
And such an effort has to take in hand all the circumference of our being, and to fix thoughts that wander, and to still wishes that clamour, and to empty hearts that are full of earthly loves, and to clear a space in minds that are crammed with thoughts about the transient and the near, in order that the mind may keep in steadfast contemplation of Jesus, and the heart may be bound to Him by cords of love that are not capable of being snapped, and scarcely of being stretched, and the will may in patience stand saying, Speak, Lord! for Thy servant heareth'; and the whole tremulous nature may be rooted and built up in and on Him. Ah, brother! if we understand all that goes to the fulfilment of that one sweet and merciful injunction, Abide in Me,' we shall recognise that there is the field on which Christian effort is mainly to be occupied.
But that is not all. For there must be likewise the effort to appropriate, and still more to manifest in conduct, the fruit-bringing properties of that indwelling light. Giving all diligence add to your faith.' Having these promises, let us cleanse ourselves from all filthiness of flesh and spirit, perfecting holiness in the fear of the Lord.' We are often told that just as we trust Christ for our forgiveness and acceptance, so we are to trust Him for our sanctifying and perfecting. It is true, and yet it is not true. We are to trust Him for our sanctifying and our perfecting. But the faith which trusts Him for these is not a substitute for effort, but it is the foundation of effort. And the more we rely on His power to cleanse us from all evil, the more are we bound to make the effort in His power and in dependence on Him, to cleanse ourselves from all evil, and to secure as our own the natural outcomes of His dwelling within us, which are the fruits of the light.'
