text: I believe in God because in studying physics, you find that everything has an explanation.  If you drop a ball from 100 meters, you can calculate how long it will take to hit the ground.  All you need to know is the acceleration of gravity, the air resistance, etc.  But you can't do that with humans.  Even if a supercomputer plotted out every atom in a person's body, physics, or any science for that matter, couldn't account for his actions.  Therefore, there must be something that gives us choice.  I don't think God controls us, but he did give us free agency, and we will be judged according to how we use our free agency.
