1 John 3:5

“And ye know that he was manifested, &c.] This is a truth of the Gospel the saints were well instructed in and acquainted with; that Jesus Christ, the Word and Son of God, who is here meant, who was with the Father, and lay in his bosom from all eternity, was in the fulness of time made manifest in the flesh, or human nature, by assuming it into union with his divine person; in which he came and dwelt among men, and became visible to them: the end of which manifestation was, to take away our sins; as the antitype of the scape goat, making reconciliation and satisfaction for them, through the sacrifice of himself; which was doing what the blood of bulls and goats, or any legal sacrifices or…”

“Additional proof of the incompatibility of sin and sonship; the very object of Christ's manifestation in the flesh was to take away (by one act, and entirely, aorist) all sins, as the scapegoat did typically. and--another proof of the same. in him is no sin--not "was," but "is," as in Jo1 3:7, "He is righteous," and Jo1 3:3, "He is pure." Therefore we are to be so.”

“And ye know that he was manifested - The Lord Jesus, the Son of God. “You know that he became incarnate, or appeared among people, for the very purpose of putting an end to sin,” Matthew 1:21. Compare the notes at 1 Timothy 3:16. This is the “second” argument in this paragraph, 1 John 3:4-10, by which the apostle would deter us from sin. The argument is a clear one, and is perhaps the strongest that can be made to bear on the mind of a true Christian - that the Lord Jesus saw sin to be so great an evil, that he came into our world, and gave himself to the bitter sorrows of death on the cross, to redeem us from it. To take away our sins - The essential argument here is, that the whole work of…”

“And ye know that he - Christ. Was manifested - That he came into the world for this very purpose. To take away our sins - To destroy them all, root and branch, and leave none remaining. And in him is no sin - So that he could not suffer on his own account, but to make us as himself. 1 John 3:6”
