1 John 2:21–23

[21] I write to you, not because you do not know the truth, but because you know it, and because no lie is of the truth. [22] Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. [23] No one who denies the Son has the Father. Whoever confesses the Son has the Father also. (ESV)
