III. Lastly, we have here the branches abiding in the Vine, and therefore fruitful. Our Lord deals with the little group of His disciples as incipiently and imperfectly, but really, cleansed through 'the word which He has spoken to them,' and gives them His exhortation towards that conduct through which the cleansing and the union and the fruitfulness will all be secured. 'Now ye are clean: abide in Me and I in you. As the branch cannot bear fruit of itself except it abide in the vine, no more can ye except ye abide in Me.' Union with Christ is the condition of all fruitfulness. There may be plenty of activity and yet barrenness. Works are not fruit. We can bring forth a great deal 'of ourselves,' and because it is of ourselves it is nought. Fruit is possible only on condition of union with Him. He is the productive source of it all. There is the great glory and distinctive blessedness of the Gospel. Other teachers come to us and tell us how we ought to live, and give us laws, patterns and examples, reasons and motives for pure and noble lives. The Gospel comes and gives us life, if we will take it, and unfolds itself in us into all the virtues that we have to possess. What is the use of giving a man a copy if he cannot copy it? Morality comes and stands over the cripple, and says to him, 'Look here! This is how you ought to walk,' and he lies there, paralysed and crippled, after as before the exhibition of what graceful progression is. But Christianity comes and bends over him, and lays hold of his hand, and says, 'In the name of Jesus Christ of Nazareth, rise up and walk,' and his feet and ankle bones receive strength, and 'he leaps, and walks, and praises God.' Christ gives more than commandments, patterns, motives; He gives the power to live soberly, righteously, and godly, and in Him alone is that power to be found. Then note that our reception of that power depends upon our own efforts. 'Abide in Me and I in you.' Is that last clause a commandment as well as the first? How can His abiding in us be a duty incumbent upon us? But it is. And we might paraphrase the intention of this imperative in its two halves, by--Do you take care that you abide in Christ, and that Christ abides in you. The two ideas are but two sides of the one great sphere; they complement and do not contradict each other. We dwell in Him as the part does in the whole, as the branch does in the vine, recipient of its life and fruit-bearing energy. He dwells in us as the whole does in the part, as the vine dwells in the branch, communicating its energy to every part; or as the soul does in the body, being alive equally in every part, though it be sight in the eyeball, and hearing in the ear, and colour in the cheek, and strength in the hand, and swiftness in the foot.
