Jesus of Nazareth claimed and was proven to be the Messiah of Old Testament prophecy. He also claimed to be God—a fact that the Old Testament prophecies alluded to, but was not fully understood until Jesus came. His disciples began to understand and accept who Jesus was during His earthly ministry because of His miracles, His teachings, and His fulfillment of prophecy. The ultimate proof for them (and for us) is the resurrection of Jesus Christ—predicted both by him and by the prophets of old.
