cwk9, to answer your point 5. God knows all. He is the author of the Bible and knew then end before the beginning. It's hard to understand but it's true.

Onto point 6, read Proverbs in the Bible. A scripture from the last part of the book goes something like this, for it is God who concealeth and a king that searcheth out. So, God conceals this code that is specially designed for the end times when he know we will only have the technology now to decode it. It's purpose is to further prove the Bible's factuality and to show that God is all knowing. Why is it so hard to believe? Spies use codes that only the recieving party can read in clear, plain text.
