I John 2:22-23 and 28

"Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son."

"Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also."

"And now, little children, abide in Him, that when He appears, we may have confidence and not be ashamed before Him at His coming."
