'Denies' in the Bible

But whoever denies me before people, I also will deny him before my Father [who is] in heaven.

but the one who denies me before people will be denied before the angels of God.

Who is the liar except the one who denies that Jesus is the Christ? This person is the antichrist, the one who denies the Father and the Son.

Everyone who denies the Son does not have the Father [either]; the one who confesses the Son has the Father also.
