1 John 2:23 in the King James Version
Whosoever denieth the Son, the same hath not the Father: but he that acknowledgeth the Son hath the Father also.
Context
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 Whoever denies the Son doesn’t have the Father. He who confesses the Son has the Father also.
24 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.
