The Christain walk depends on a strong belief in God's reality. But unless the Bible can be somehow verified, it's no more than any other book of stories. And being such, the things that can't be verified, like heaven, God's constant Presense, and His provision, can hold no interest. Our task, then, is to find as much verifiable evidence as possible, to help us act on those UN verifiable concepts. Just because the same event is prophesied in two different places doesn't make it true.
Objective evidence is always best.
When we're sure we couldn't have made up something, we have more confidence in it. Of course, the best places to check prophecy are history and archeology. More than a century before Darius the Great commisioned Behistun rock, however, the Assyrians were watching their borders. Their enemies the Urartians and the Medes may start gathering an army. The Assyrians wanted to know everthing that was going on with their foes.
