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.
