Reason and Revelation

Daniel 4:33 Immediately the word was fulfilled against Nebuchadnezzar. He was driven from among men and ate grass like an ox, and his body was wet with the dew of heaven till his hair grew as long as eagles' feathers, and his nails were like birds' claws. 34 At the end of the days I, Nebuchadnezzar, lifted my eyes to heaven, and my reason returned to me, and I blessed the Most High, and praised and honored him who lives forever, for his dominion is an everlasting dominion,and his kingdom endures from generation to generation;...
36 At the same time my reason returned to me, and for the glory of my kingdom, my majesty and splendor returned to me. ... and those who walk in pride [God] is able to humble.

The tension maintained between reason and faith comes down to this. Reason rests on the divine ordering of all things by God himself. This fact must be taken on faith, but is an essential given to "believe" in reason itself.

If God exists, it is reasonable to believe in God.
If God does not exist, it is not reasonable to believe in Reason.
