“AND IF ANY MAN SIN, WE HAVE AN ADVOCATE WITH THE FATHER, JESUS CHRIST THE RIGHTEOUS.”— I JOHN 2:1.
That the apostle might obtain due regard from those to whom he wrote, touching the things about which he wrote, he tells them that he received not his message to them at second or third hand, but was himself an eye and ear witness thereof — “That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the word of life, (for the life was manifested, and we have seen it, and bear witness and show unto you that eternal life, which was with the Father, and was manifested unto us;) that which we have seen and heard, declare we unto you” [I John 1:1-3].
Having thus told them of his ground for what he said, he proceeds to tell them also the matter contained in his errand-to wit, that he brought them news of eternal life, as freely offered in the word of the gospel to them; or rather, that that gospel which they had received would certainly usher them in at the gates of the kingdom of heaven, were their reception of it sincere and in truth — for, saith he, then “the blood of Jesus Christ the Son of God cleanseth you from all sin.”
Having thus far told them what was his errand, he sets upon an explication of what he had said, especially touching our being cleansed from all sin — “Not,” saith he, “from a being of sin; for should we say so, we should deceive ourselves,” and should prove that we have no truth of God in us, but by cleansing, I mean a being delivered from all sin, so as that none at all shall have the dominion over you, to bring you down to hell; for that, for the sake of the blood of Christ, all trespasses are forgiven you.
This done, he exhorts them to shun or fly sin, and not to consent to the motions, workings, enticings, or allurements thereof, saying, “I write unto you that ye sin not.” Let not forgiveness have so bad an effect upon you as to cause you to be remiss in Christian duties, or as to tempt you to give, way to evil. Shall we sin because we are forgiven? or shall we not much matter what manner of lives we live, because we are set free from the law of sin and death? God forbid. Let grace teach us another lesson, and lay other obligations upon our spirits. “My little children,” saith he, “these things write I unto you, that ye sin not.” What things? Why, tidings of pardon and salvation, and of that nearness to God, to which you are brought by the precious blood of Christ. Now, lest also by this last exhortation he should yet be misunderstood, he adds, “And if any man sin, we have an Advocate with the rather, Jesus Christ the righteous.” I say, he addeth this to prevent desponding in those weak and sensible Christians that are so quick of feeling and of discerning the corruptions of their natures; for these cry out continually that there is nothing that they do but it is attended with sinful weaknesses.
