The High Priest Caiaphas has just asked Jesus directly if he is the Messiah, the Son of God, and for the first time, Jesus has responded. In his response, he has gone way beyond identifying himself as the Messiah. In using the name, “I Am,” Jesus has unequivocally identified himself as being Jehovah God.
Not only that, but Jesus has identified himself as the divine Son of Man who defeats his enemies and brings about the Kingdom of God in the prophecies of Daniel. Plain truth is often met by pure anger, and that is precisely what happens next.
