1 John 2:4; 1 John 2:22

1 John 2:4

4 If someone claims, “I know God,” but doesn’t obey God’s commandments, that person is a liar and is not living in the truth.

1 John 2:22

22 And who is a liar? Anyone who says that Jesus is not the Christ. Anyone who denies the Father and the Son is an antichrist.
