The meaning of being a Christian is that, in return for the gift of a whole Christ, I give my whole self to Him. 'Why call ye me Lord! Lord! and do not the things which I say?' If He is what He assuredly is to every one of us, nothing can be plainer than that we are thereby bound by obligations which are not iron, but are more binding than if they were, because they were woven out of the cords of love and the bands of a man, bound to serve Him supremely, Him only, Him always, Him by the suppression of self, and the making His pleasure our law. II. Now, secondly, let me ask you to notice that we have here the all-sufficient guide for practical life. It sounds very mystical, and a trifle vague, to say, Do everything to please Jesus Christ. It is all-comprehensive; it is mystical in the sense that it goes down below the mere surface of prescriptions about conduct. But it is not vague, and it is capable of immediate application to every part, and to every act, of every man's life. For what is it that pleases Jesus Christ? His own likeness; as, according to the old figure--which is, I suppose, true to spiritual facts, whether to external facts or not--the refiner knows that the metal is ready to flow when he can see his own face in it. Jesus Christ desires most that we should all be like Him. That we are to bear His image is as comprehensive, and at the same time as specific, a way of setting forth the sum of Christian duty, as are the words of my text. The two phrases mean the same thing. And what is the likeness to Jesus Christ which it is thus our supreme obligation and our truest wisdom and perfection to bear? Well! we can put it all into two words--self-suppression and continual consciousness of obedience to the Divine will. The life of Jesus Christ, in its brief records in Scripture, is felt by every thoughtful man to contain within its narrow compass adequate direction for, and to set forth the ideal of, human life. That is not because He went through all varieties of earthly experience, for He did not. The life of a Jewish peasant nineteen centuries ago was extremely unlike the life of a Manchester merchant, of a college professor, of a successful barrister, of a struggling mother, in this present day. But in the narrow compass of that life there are set forth these two things, which are the basis of all human perfection--the absolute annihilation of self-regard, and the perpetual recognition of a Divine will. These are the things which every Christian man and woman is bound by the power of Christ's Cross to translate into the actions correspondent with their particular circumstances. And so the student at his desk and the sailor on his deck, the miner in his pit, the merchant on 'Change, the worker in various handicrafts, may each be sure that they are doing what is pleasing to Christ if, in their widely different ways, they seek to do what they can do in all the varieties of life--crucify self, and commune with God.
