He that says, I know him, and keeps not his commandments, is a liar, and the truth is not in him.
All Commentaries on 1 John 2:4 Go To 1 John 2
George Leo Haydock
AD 1849
He that says he knoweth him To know, in this and many other places, is not taken for a speculative knowledge alone, but is joined with a love of God, and an earnest desire of serving him and keeping his commandments. (Witham)
