Williams(i)
5 You know that He appeared to take our sins away, and that there is no sin in Him.
6 No one who continues to live in union with Him practices sin. No one who practices sin has ever seen Him or come to know Him.
7 Dear children, avoid letting anyone lead you astray. Whoever practices doing right is upright, just as He is upright.
8 Whoever practices sin belongs to the devil, because the devil has practiced sin from the beginning. This is why the Son of God appeared, to undo the devil's works.
