'I write no new commandment unto you, but an old commandment which ye had from the beginning.... Again, a new commandment I write unto you, which thing is true in him and in you.' -- 1 John ii.7, 8.

The simplest words may carry the deepest thoughts. Perhaps angels and little children speak very much alike. This letter, like all of John's writing, is pellucid in speech, profound in thought, clear and deep, like the abysses of mid-ocean. His terms are such as a child can understand; his sentences short and inartificial: he does not reason, he declares; he has neither argument nor rhetoric, but he teaches us the deepest truths, and shows us that we get nearer the centre by insight than by logic.

Now the words that I have taken for my text are very characteristic of this Apostle's manner. He has a great, wide-reaching truth to proclaim, and he puts it in the simplest, most inartificial manner, laying side by side two artless sentences, and stimulates us by the juxtaposition, leading us to feel after, and so to make our own, the large lessons that are in them. Let me, then, try to bring these out.

I. And the first one that strikes me is -- 'the word' is 'a commandment.'

Now, by 'the word' here the Apostle obviously means, since he speaks about it as that which these Asiatic Christians 'heard from the beginning,' the initial truth which was presented for their acceptance in the story of the life and death of Jesus Christ. That was 'the word' and, says he, just because it was a history it is a commandment; just because it was the Revelation of God it is a law. God never tells us anything merely that we may be wise. The purpose of all divine speech, whether in His great works in nature, or in the voices of our own consciences, or in the syllables that we have to piece together from out of the complicated noises of the world's history, or in this book, or in the Incarnate Word, where all the wandering syllables are gathered together into one word -- the purpose of all that God says to men is primarily that they may know, but in order that, knowing, they may do; and still more that they may be. And so, inasmuch as every piece of religious knowledge has in it the capacity of directing conduct, all God's word is a commandment.

And, if that is true in regard to other revelations and manifestations that he has made of Himself, it is especially true in regard to the summing-up of all in the Incarnate Word, and in His words, and in the words that tell us of His life and of His death. So whatever truths there may be, and there are many, which, of course, have only the remotest, if any, bearing upon life and conduct, every bit of Christian truth has a direct grip upon a man's life, and brings with it a stringent obligation.

Now, the Revelation of God in Jesus Christ, 'the Word which ye heard from the beginning,' which, I suppose, would roughly correspond with what is told us in our four Gospels; the word which these Asiatic Christians heard at first, the good news that was brought to them in the midst of their gropings and peradventures, commanded, in the first place, absolute trust, the submission of the will as well as the assent of the understanding. But also it commanded imitation, for Jesus Christ was revealed to them, as He is revealed to us, as being the Incarnate realisation of the ideal of humanity; and what He is, the knowledge that He is that, binds us to try to be in our turn.

And more than that, brethren, the Cross of Christ is a commandment. For we miserably mutilate it, and sinfully as well as foolishly limit its application and its power, if we recognise it only -- I was going to say mainly -- as being the ground of our hope and of what we call our salvation, and do not recognise it as being the obligatory example of our lives, which we are bound to translate into our daily practice. Jesus Christ Himself has told us that in many a fashion, never more touchingly and wondrously than when in response to the request of a handful of Greeks to see Him, He answered with the word which not only declared what was obligatory upon Him, but what was obligatory upon us all, and for the want of which all the great endowments of the Greek mind at last rotted down into sensuousness, when He said, 'Except a corn of wheat fall into the ground and die, it abideth alone, but if it die it bringeth forth much fruit' and then went on to say, 'he that loveth his life shall lose it.'

So, then, brethren, 'the word which ye heard at the beginning,' the story of Christ, His life and His death, is a stringent commandment. Now, this is one of the blessings of Christianity, that all which was hard and hopeless, ministering to despair sometimes, as well as stirring to fierce effort at others, in the conception of law or duty as it stands outside us, is changed into the tender word, 'if ye love Me, keep My commandments.' If any man serve Me, let him ... 'follow Me.' It is a law; it is 'the law of liberty.' So you have not done all that is needful when you have accepted the teaching of Christ in the Scriptures and the teaching of the Scriptures concerning Christ. Nor have you done all that is needful when clasping Him, and clinging simply to His Cross, you recognise in it the means and the pledge of your acceptance with God, and the ground and anchor of all your hope. There is something more to be done. The Gospel is a commandment, and commandments require not only assent, not only trust, but practical obedience. The 'old commandment' is the 'word which ye heard from the beginning.'

II. The old Christ is perpetually new.

The Apostle goes on, in the last words of my text, to say, 'Which thing' (viz., this combination of the old and the new) 'is true in Him and in you.' 'True in Him' -- that is to say, Christ, the old Christ that was declared to these Asiatic Christians as they were groping amidst the illusions of their heathenism, is perpetually becoming new as new circumstances emerge, and new duties are called for, and new days come with new burdens, hopes, possibilities, or dangers. The perpetual newness of the old Christ is what is taught here.

Suppose one of these men in Ephesus heard for the first time the story that away in Judea there had lived the manifestation of God in the flesh, and that He, in His wonderful love, had died for men, that they might be saved from the grip of their sins. And suppose that man barely able to see, had yet seen that much, and clutched at it. He was a Christian, but the Christ that he discerned when he first discerned Him through the mists, and the Christ that he had in his life and in his heart, after, say, twenty years of Christian living, are very different. The old Christ remained, but the old Christ was becoming new day by day, according to the new necessities and positions. And that is what will be our experience if we have any real Christianity in us. The old Christ that we trusted at first was able to do for us all that we asked Him to do, but we did not ask Him at first for half enough, and we did not learn at first a tithe of what was in Him. Suppose, for instance, some great ship comes alongside a raft with ship-wrecked sailors upon it, and in the darkness of the night transfers them to the security of its deck. They know how safe they are, they know what has saved them, but what do they know compared with what they will know before the voyage ends of all the reservoirs of power and stores of supplies that are in her? Christ comes to us in the darkness, and delivers us. We know Him for our Deliverer from the first moment, if we truly have grasped Him. But it will take summering and wintering with Him, through many a long day and year, before we can ever have a partially adequate apprehension of all that lies in Him.

And what will teach us the depths of Christ, and how does He become new to us? Well, by trusting Him, by following Him, and by the ministry of life. Some of us, I have no doubt, can look back upon past days when sorrow fell upon us, blighting and all but crushing; and then things that we had read a thousand times in the Bible, and thought we had believed, blazed up into a new meaning, and we felt as if we had never understood anything about them before. The Christ that is with us in the darkness, and whom we find able to turn even it, if not into light, at least into a solemn twilight not unvisited by hopes, that Christ is more to us than the Christ that we first of all learnt so little to know. And life's new circumstances, its emerging duties, are like the strokes of the spade which clears away the soil, and discloses the treasure in all its extent which we purchased when we bought that field. We buy the treasure at once, but it takes a long time to count it. The old Christ is perpetually the new Christ.

So, brethren, Christian progress consists not in getting away from the original facts, the elements of the Gospel, but it consists in penetrating more deeply into these, and feeling more of their power and their grasp. All Euclid is in the definitions and axioms and postulates at the beginning. All our books are the letters of the alphabet. And progress consists, not in advancing beyond, but in sinking into, that initial truth, 'God was in Christ reconciling the world unto Himself.'

I might say a word here as to another phase of this perpetual newness of the old Christ -- viz., in His adaptation to deal with all the complications and perplexities and problems of each successive age. It has taken the Church a long, long time to find out and to formulate, rightly or wrongly, what it has discovered in Jesus. The conclusions to be drawn from the simple Gospel truth, the presuppositions on which it rests, require all the efforts of all the Church through all the ages, and transcend them all. And I venture to say, though it may sound like unsupported dogma, that for this generation's questionings, social, moral, and political, the answer is to be found in Him. He, and He only, will interpret each generation to itself, and will meet its clamant needs. There is none other for the world to-day but the old Christ with the new aspect which the new conditions require.

Did it ever strike you how remarkable it is, and, as it seems to me, of how great worth as an argument for the truth of Christianity it is, that Jesus Christ comes to this, as to every generation, with the air of belonging to it? Think of the difference between the aspect which a Plato or a Socrates presents to the world to-day, and the aspect which that Lord presents. You do not need to strip anything off Him. He committed Himself to no statements which the progress of thought or knowledge has exploded. He stands before the world to-day fitting its needs as closely as He did those of the men of His own generation. The old Christ is the new Christ.

III. Lastly, in the Christian life the old commandment is perpetually new.

'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, to-day, and for ever,' the old Christ whom, amid the shadows of earth, we tried to love and copy.
