1 John 2:4

4Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person.

4The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him;

4The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him;

4Whoever says, “I have come to know Him,” but does not habitually keep [focused on His precepts and obey] His commandments (teachings), is a liar, and the truth [of the divine word] is not in him.

4If anyone says, “I know Him,” but does not keep His commandments, he is a liar, and the truth is not in him.

4Suppose someone says, “I know him.” But suppose this person does not do what God commands. Then this person is a liar and is not telling the truth.
