1 John 2:21-23 New English Translation (NET Bible)
21 I have not written to you that you do not know the truth, but that you do know it, and that no lie is of the truth. 22 Who is the liar but the person who denies that Jesus is the Christ? This one is the antichrist: the person who denies the Father and the Son. 23 Everyone who denies the Son does not have the Father either. The person who confesses the Son has the Father also.
