Isaiah 9:6 (ESV) For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.

This prophesy was made 800 years before Christ was born.  Without a doubt, we know this event occurred. If this event occurred as prophesied in the Bible, why would we ever doubt

anything else in the Bible? Even though the OT prophets did not fully understand what God told them, they believed what God said to be true and continue to search the Scripture.
