1 John 2:21-23

21I have not written to you because you lack knowledge of the truth, but because you have it, and because no lie comes from the truth. 22Who is the liar, if it is not the one who denies that Jesus is the Christ? This is the antichrist, who denies the Father and the Son. 23Whoever denies the Son does not have the Father, but whoever confesses the Son has the Father as well.
