Except that Christ carefully fulfilled the prophecies.
He was the promised Messiah from the house of David.
He was the Son of Man who God told us was His Son, and He is the Lord.
His claim for being the final prophet is legitamite, any other person's claim to be this prophet is not legitamite.
Muhammed and Starjade have not fulfilled any prophecies.
You're only men claiming prophethood, well no prophet can supercede the Messiah!
