1 John 2:22-24

2:22 Who is the liar but the person who denies that Jesus is the Christ? This one is the antichrist: the person who denies the Father and the Son. 2:23 Everyone who denies the Son does not have the Father either. The person who confesses the Son has the Father also.

2:24 As for you, what you have heard from the beginning must remain in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.
