When you run into someone and they start slamming the bible and telling you how meaningless its contents are - drop this little tidbit on them:
Ask them, if the bible is so full of nonsense, how come thousands of years before scientists made it "official" that the earth was round - the bible made it clear that it was?
Have them read Isaiah 40:22 - "He sits enthroned above the circle of the earth, and its people are like grasshoppers. He stretches out the heavens like a canopy, and spreads them out like a tent to live in."
Be warned though - people whose minds have been so thoroughly darkened will tell you that "circle" doesn't mean round. Yeah, just like red doesn't mean red, and black doesn't mean black right?
