'Jesus is the Christ' in the Bible

but these [things] are recorded in order that you may believe that Jesus is the Christ, the Son of God, and that [by] believing you may have life in his name.

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 believes that Jesus is the Christ has been fathered by God, and everyone who loves {the father} also loves the [child] fathered by him.
