1 John 2:21-23

21I do not write to you because you do not know the truth, but because you do know it and because no lie comes from the truth. 22Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son.

23No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.
