The blood of Jesus Christ cleanseth from all sin.' Now if you will notice the whole context, and eminently the words a couple of verses after my text, you will see that the cleansing here meant is not the cleansing of forgiveness, but the cleansing of purifying. For the two things are articulately distinguished in the ninth verse: He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.' So, to use theological terms, it is not justification, but sanctification that is meant here.
Then there is another thing to be noticed, and that is that when the Apostle speaks here about the blood of Christ, he is not thinking of that blood as shed on the Cross, the atoning sacrifice, but of that blood as transfused into the veins, the source there of our new life. The Old Testament says that the blood is the life.' Never mind about the statement being scientifically correct; it conveys the idea of the time, which underlies a great deal of Old and New Testament teaching. And when John says the blood of Jesus cleanses from all sin,' he says just the same thing as his brother Paul said, the law of the spirit of life in Jesus Christ makes me free from the law of sin and death.' That is to say, a growing cleansing from the dominion and the power of sin is granted to us, if we have the life of Jesus Christ breathed into our lives. The metaphor is a very strong one. They tell us--I know nothing about the truth of it--that sometimes it has been possible to revive a moribund man by transfusing into his veins blood from another. That is a picture of the only way by which you and I can become free from the tyranny that dominates us. We must have the life of Christ as the animating principle of our lives, the spirit of Jesus emancipating us from the power of sin and death.
So you see, there are two aspects of Christ's great work set before us under that one metaphor of the blood in its two-fold form, first, as shed for us sinners on the Cross; second, as poured into our veins day by day. That works progressive cleansing. It covers the whole ground of all possible iniquity. Pardon is much, purifying is more. The sacrifice on the Cross is the basis of everything, but that sacrifice does not exhaust what Christ does for us. He died for our sins, and lives for our sanctifying. He died for us, He lives in us. Because He died, we are forgiven; because He lives, we are made pure. Only remember John's if.' The blood of Jesus will progressively cleanse us until it has cleansed us from all sin, on condition that we walk in the light,' not otherwise. If the main direction of our lives is towards the light; if we seek, by aspiration and by effort, and by deliberate choice, to live in holiness, then, and not else, will the power of the life of Jesus Christ deliver us from the power of sin and death.
Now, my text presupposes that the people to whom it is addressed, and whom it concerns, have already passed from darkness into light, if not wholly, yet in germ. But for those who have not so passed, there is something to be said before my text. And John says it immediately; here it is, If any man sin we have an Advocate with the Father, Jesus Christ the righteous, and He is the propitiation for our sins; and not for our sins only, but for the whole world.' So we have to begin with the blood shed for us, the means of our pardon, and then we have the advance of the blood sprinkled on us, the means of our cleansing. If by humble faith we take the dying Lord for our Saviour, and the channel of our forgiveness, we shall have the pardon of our sins. If we listen to the voice that says, Ye were sometime darkness, but now are ye light in the Lord. Walk as children of the light,' we shall have fellowship with the living Lord, and daily know more and more of the power of His cleansing blood, making us meet to be partakers of the inheritance of the saints in light.'
