I may be a religious person, but i'm also a sane person to know that my brain isn't me, my body, isn't me. The mind is a very complex thing. You keep talking about cause and effect, but i feel like you don't really understand what these mean. You take for granted what good ole sammy sam says because he sounds sooooooo smart. In all seriousness though, I can understand why the atheistic world view cannot accept the idea of free will, because it simple contradicts it. If we truly live in a material world with nothing else existing then it would make sense that free will cannot exist because the mind cannot exist. However i want you to take this case as an interesting prospect. They did a study where they performed an open brain surgery on a patient who was still conscious. The surgeon activated a part of his brain that triggered his arm to jerk forwards. Then the surgeon asked the patient why he just jerked his arm like that, the patient responded it was not me who jerked my arm but something else made it do it. For the longest time people though that your brain was the same as your consciousness, then they realized that it isn't that simple. You're consciousnesses or the "mind" is actually an extremely complex thing to figure out. Now some people believe that the mind is your soul, i personally believe it a bit of both. If we want to talk science, then the science is clear that we have choices which are not dictated. You have the mind and logic to make judgement about the world you see around you. If you choose not to become religious, this was based solely on your own decision that was not dictated by anyone else. You may have inclinations which can lead to make one decision over the other, but the decision is still yours to make. Just because you make these decisions through chemicals happening in your brain does not mean your mind did not have anything to contribute to it. Think about it this way. Your mind is the starting point of anything you do, then your mind triggers your brain to do it's thing and to move the necessary body parts it needs to, then the body goes and does what the brain tells it.
