The Old Testament contains sixty major prophecies and 270 ramifications about the Messiah. Jesus fulfilled every one of these predictions. The probability of Jesus fulfilling merely eight of the sixty major prophecies is 1 in 100,000,000,000,000,000.
To put these odds in perspective, imagine that the entire state of Texas is covered with silver dollars two feet deep and one of them is marked. All of the silver dollars are then thoroughly mixed. A blindfolded man is then instructed to reach down and pick up the marked coin on his first try. The chances of that occurring are the same as Jesus fulfilling just eight of the sixty major prophecies. But consider, He fulfilled them all! The probability of Jesus not being the Messiah is mathematically impossible.
