But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus Christ, his Son, cleanses us from all sin.
Secondly, this passage shews that the gratuitous pardon of sins is given us not only once, but that it is a benefit perpetually residing in the Church, and daily offered to the faithful. For the Apostle here addresses the faithful; as doubtless no man has ever been, nor ever will be, who can otherwise please God, since all are guilty before him; for however strong a desire there may be in us of acting rightly, we always go haltingly to God. Yet what is half done obtains no approval with God. In the meantime, by new sins we continually separate ourselves, as far as we can, from the grace of God. Thus it is, that all the saints have need of the daily forgiveness of sins; for this alone keeps us in the family of God.
