1 John 2:21-23

I have not written to you because you don’t know the truth, but because you do know it, and because no lie comes from the truth. Who is the liar, if not the one who denies that Jesus is the Christ? This one is the antichrist: the one who denies the Father and the Son. No one who denies the Son has the Father; he who confesses the Son has the Father as well.
