1 John 2:23

Whosoever denieth the Son, the same hath not the Father: he that confesseth the Son hath the Father also.

The denial of the Son of God, through failure to confess him, results in the loss of the Father, because only the divine Son can reveal the Father. "No one cometh unto God but by me," he said. On the other hand, as John stated it conversely, the meaningful confession of Jesus Christ as the Son of God leads to a full knowledge of God in the forgiveness of sins.
