'My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: 2. And He is the propitiation for our sins: and not for ours only, but also for the sins of the whole world. 3. And hereby we do know that we know Him, if we keep His commandments. 4. He that saith, I know Him, and keepeth not His commandments, is a liar, and the truth is not in him. 5. But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in Him. 6. He that saith he abideth in Him ought himself also so to walk, even as He walked.'—1 John i. 5-ii. 6.
John is the mystic among the New Testament writers. He dwells much on the immediate union of the soul with God, and he has little to say about institutions and rites. His method is not to argue, but to utter deep, simple propositions which convince by their own light. But he is also intensely eager for plain, practical morality, and in that respect sets the example which, unfortunately, too many of the more mystical types of Christian teaching have failed to follow. To him the outcome and test of all deep hidden union with God is righteousness in life.
The blending of these two elements, which is the very keynote of this letter, is wonderfully set forth in this passage. They would require much more space than we command for their treatment, for every clause is weighty as gold. We can but skim the surface, and try to bring out the salient points.
I. We have, first, a wonderful gathering up of the whole gospel message into one utterance as to the essential nature of God. Light is in all languages the symbol of knowledge, of joy, of purity. It is the source of life. Its very nature is to ray itself out into and conquer darkness. Its splendor dazzles every eye; all things rejoice in its beams. Darkness is the type of ignorance, of sorrow, of sin. But, whilst the symbol is thus rich in manifold revelations, probably purity and self-communication are the predominating ideas here.
John has been honoured to give the world the three great revelations that God is spirit, is light, is love. And this profound saying in some sense includes both the others, inasmuch as light, which to the popular mind is most widely apart from matter, may well stand for the emblem of spirit, and, since to radiate is its inseparable quality, does represent in symbol the delight in imparting Himself, which is the very heart of the declaration that God is love. If, then, we grasp these two thoughts of absolute purity and of self-impartation as the very nature and property of God, John tells us that we grasp the kernel of the Gospel.
And he thinks that men never will grasp them certainly unless a 'message' from God, a definite revelation in historical fact, certifies them. We may hope or doubt, or desire, but we cannot be sure that God is light unless he tells us so by unmistakable act. John knew what act that was—the sending of His only-begotten Son. To the positive statement John, in his usual manner, appends an emphatic negative one: 'Darkness is not in him, no, not in any way.' He is light, all light, only light.
II. With characteristic moral earnestness, John passes at once to the practical effects which the message is meant to have. We are not told what God is simply that we may know, but that, knowing, we may do and be. If He is light, two things will follow in those who are in union with Him—they will walk in light, and they will in His light see their own evil. John deals with these two consequences in verses 6-10—the former in verses 6 and 7; the latter in verses 8-10. The parallelism in the construction of these two sets of verses is striking:
| Verses 6, 7. | Verses 8, 9. |
| If we say | If we say |
| that we have fellowship with Him, and walk in darkness, | that we have no sin |
| we lie, and do not the truth. | we deceive ourselves, and the truth is not in us. |
| But if we walk in the light, as He is in the light, | If we confess our sins, |
| we have fellowship one with another. | He is faithful and righteous to forgive us our sins, |
| and the blood of Jesus His Son cleanseth us from all sin. | and to cleanse us from all unrighteousness. |
As to the former of these two paragraphs, the underlying thought is that fellowship with God necessarily involves moral likeness to Him. Worship is always aspiration after, and conformity to, the character of the god worshipped, and there can be no true communion with a God who is light unless the worshipper walks in light. In plain language, all high-flying pretensions to communion with God must verify themselves by practical righteousness. That cuts deep into an emotional religion, which has much to say about raptures and the like, but produces little purifying effect on the humble details of daily life.
There are always professing Christians who talk of their blessed experiences, and woefully fail in prosaic virtues. It is a pity that a man should hold his head so high that he does not look to keep his feet out of the mud. Such a profession is for the most part tainted with more or less conscious falsehood, and is always a proof that the truth—the sum of God's revelation—is not operative in the man; that he is not turning his belief into act, as all belief should be. On the other hand, the true relation resulting from the message is that we should walk in the light, as He is in it.
