The New Testament reveals that what was foretold in the Old Testament that a Messiah was to come. He came NOT to change the law and the prophets but to fulfill them. The Messiah, Jesus Christ, is the only one who has proclaimed to be the true Son of God and said "I am the Truth, the Way and the Life. No one comes to the Father but through Me." None of the other prophets, Christian or not, has sacrificed his body to atone for the sins of the world. No body else has fulfilled prophecy like Jesus has.
