You know that he was revealed to take away our sins, and in him is no sin.
And in him is no sin - An additional consideration to show that we should be holy. As he was perfectly pure and spotless, so should all his followers aim to be; and none can truly pretend to be his who do not desire and design to become like him. On the personal holiness of the Lord Jesus, see the Hebrews 7:26 note, and 1 Peter 2:23 note.
