Therefore, as for you, let that remain in you which you heard from the beginning. If that which you heard from the beginning remains in you, you also will remain in the Son, and in the Father.

 2:22-23 Who is the liar but the man who denies that Jesus is the Anointed One of God? Antichrist is he who denies the Father and the Son. Anyone who denies the Son does not even have the Father; and everyone who acknowledges the Son has the Father also.
