The Bible is Hearsay
Note i said hearsay and not heresy.
Thomas Paine a great American wrote in his essay "The Age of Reason" why he believed in God but not in any religion. You can google and find his essay online easily. In fact, most of the founding fathers were Deists just like Paine.
If you want to know God, you can study his word first hand... it's called creation and it's all around you. Scientists are the true spiritual scholars because they are studying creation and trying to understand it.
Why should someone believe in the Bible over The Book of Mormons or The Koran or the guy on the street corner who yells about Xenu and the pending invasion.
It's completely irrational to believe in any of them. It is all hearsay. If faith in religion means tossing my rationality, then I have no choice but to be faithless. If the God the Christians talk about existed, he could make himself known to all of us. Then we would all have first hand knowledge of him and would have a choice to obey or disobey.
You don't need faith to know that we are small and insignificance in the cosmic sense and that life abounds in the universe and that we are apart of an amazing reality.
