You do realize, that believing the Bible is not a prerequisite for a believing God, don’t you?
One can accept the moral and spiritual lessons of the Bible without trying to believe that every single lesson in the Bible is a literal account of an actual event. Furthermore, I have never met anyone who literally believes every single word in the Bible. According to the Bible, the earth is flat and the sun, planets, and stars are stuck on the inside of a shell-like structure called the "firmament", and everything moves around the earth. Human observations tell us that the nature of the earth and its place in the universe are quite different. Which do you believe, the Bible, or the observations?
I do not say that a choice must be made, that either one must believe the physical nature of the universe is as it appears *or* one must believe that every word of the Bible is literal. But those who have been raised in a strict Creationist household do believe that such a choice *must* be made, and too often decide against their faith because their own observations show them a universe that is vastly different than that described in the Bible. However, recognizing that the Bible is mostly allegory, meant to teach us moral and spiritual lessons, gives a sense of freedom by making that choice unnecessary. There is no need to spend time and effort on trying to disbelieve every observation about the nature of the physical universe because it does not match the often contradictory descriptions in the Bible. One is even free to become a scientist and devote one's life to exploring that universe and learning new facts about God's creation the way it really exists.
