Life, in the most absolute sense, is non-sensical apart from the Bible. The God who created all things, rules all things, and controls all things is entirely consistent with the God we find in Holy Scripture.
The unbeliever is willfully and joyfully blind. He would love for the Christian to "come on down and sew your eyes shut so we can converse on the same level...." However, his life is inconsistent in that he finds huge gaps of meaning. For the skeptic 2+2=4 is complete and utter nonsense unless he borrows capital from a Christian worldview, in order to make some kind of sense of his own.
