Which thing is true.., in you.' That is to say, the commandment which ye received at the beginning,' when ye received Christ as Saviour, has in itself a power of adapting itself to all new conditions as they may emerge, and will be felt increasingly to grow stringent, and increasingly to demand more entire conformity, and increasingly to sweep its circle round the whole of human life. For this is the result of all obedience, that the conception of duty becomes more clear and more stringent. If any man will do His will' the reward shall be that he will see more and more the altitude of that will, the length and breadth and depth and height of the possible conformity of the human spirit to the Will of God. And so as we advance in obedience we shall see unreached advances before us, and each new step of progress will declare more fully how much still remains to be accomplished. In us the old commandment' will become ever new.
And not only so, but perpetually with the increasing sweep and stringency of the obligation will be felt an increasing sense of our failure to fulfil it. Character is built up, for good or for evil, by slow degrees. Conscience is quickened by being listened to, and stifled by being neglected: A little speck of mud on a vestal virgin's robe, or on a swan's plumage, will be conspicuous, while a splash twenty times the size will pass unnoticed on the rags of some travel-stained wayfarer. The purer we become, the more we shall know ourselves to be impure.
Thus, my brother, there opens out before us an endless course in which all the blessedness that belongs to the entertaining and preservation of ancient convictions, lifelong friends, and familiar truths, and all the antithetical blessedness that belongs to the joy of seeing, rising upon our horizon as some new planet with lustrous light, will be united in our experience. We shall at once be conservative and progressive; holding by the old Christ and the old commandment, and finding that both have in them endless novelty. The trunk is old; every summer brings fresh leaves. And at last we may hope to come to the new Jerusalem, and drink the new wine of the Kingdom, and yet find that the old love remains, and that the new Christ, whose presence makes the new heavens and the new earth, is the same yesterday, today, and for ever,' the old Christ whom, amid the shadows of earth, we tried to love and copy.
