It is impossible for anyone to have predicted with accuracy all the things found in the New Testament. Yet, that is exactly what we find in the prophecies of the Old Testament which point to the events recorded in the New Testament.
Who could have predicted a child to be called "Mighty God" (Isaiah 9:6), who would be born of a virgin in Bethlehem (Isaiah 7:14), who would be rejected by His own people (Isaiah 53:3), who would save only a remnant of Israel (Isaiah 37:31), who would be lead as a sheep to the slaughter (Isaiah 53:7), who would be resurrected keeping his body from seeing corruption (Isaiah 38:17)? Who could have predicted the rise and fall of kingdoms like Babylon, Nineveh, Tyre and Sidon, the fall of Jerusalem (Daniel 9:24-27), the subjugation of the Medes and Persians to the Grecians, and a fourth kingdom mightier than those at which time God would set up His kingdom (Daniel2:44)? Who could have predicted the things surrounding Jesus' death, the lots cast for his garments (Isaiah 53:12), the pierced hands and feet (Psalm 22:16), while not a bone being broken in his body like the passover lamb (Psalm 34:20)? Who could have predicted that in three days He would be raised from the dead (Hosea 6:2)? What other book shows such a united theme and such divine wisdom in predictive prophecy? These features are missing from any other book claiming to be inspired.
Even if someone could have predicted these things, who could have made them happen just as prophesied? The odds of this occurring apart from inspiration is1 in 10,000,000,000,000,000,000,000,000,000. An amazing feature found in the Old Testament is the many direct prophecies of Christ, which when combined with the miraculous events, confirm His Deity and his being part of the Godhead. This is only a small portion of the many reasons I know the Bible is inspired, accurate, truthful, and the only Guide for the follower of God today!
