Eschatos Ministry recently spent some time addressing the question about whether we can know about prophecy
HERE.
Obviously there are some things where I am in disagreement with Alan. He's more confident of his rapture timing position than I am in mine. There may be some curve balls coming but the Bible is clear regarding future Israel and a future millennium. Moreover, as Alan Kurschner notes, Jesus expected the disciples to know about Him through reading Moses and the prophets.
People like William Lane Craig and even Michael Heiser are prophecy agnostics. I find it ironic especially with Dr Heiser given that he's quite sure of some things in the Bible concerning his particular realm of interest. Perhaps in the future I might blog some more on this.

Can We Trust Prophecy?
