Based on what you are all saying in here, I'm easily one of the most far out people on the board.
I wholeheartedly believe in the Bible, Jesus, Yahweh/Jehovah, the flood, creation, walking on water, raising from the dead, etc. So much so, I've recently developed a habit of getting up around 5-6am every day to spend between 1-2 hours praying and reading the Bible.
I've seen, heard, and experienced enough at this point in my life to believe in God 100%. Now my understanding of God (his nature, plans, etc), the meaning of Bible verses (particularly of the ancient variety) and exactly where things are headed is something that I do not know and believe is really unknowable this side of heaven. Basically, I don't know the truth of everything, but I'm committed to seeking it out and am certain that God exists and has the keys to the truth of our existence, origins, meaning, etc. For me, nothing in the world makes sense without that faith in God.
If my base premise is right, that the God of the Bible (the Great I Am, Yahweh, Jehovah) is real and the one true creator God, then the rest of it is really pretty easy to grasp. He can do anything he wants with his creation, he has intervened at times and not others as he sees fit and has inspired the Bible to be written as he wanted it and preserved it as he saw fit.
Y'all can call me crazy or whatever, but most of your big picture beliefs really aren't proven, any better, or even fully hashed out and I believe my beliefs are at least "knowable" just not provable.
