You are contradicting your self if you believe in God and then you say we are the one who decide to be good or bad.
Then answer this questions:
1. Why do you believe in God? in other words what benifits do you get from believing in God?
2. How do you know if there is God?
3. If you believe in God then what will God do to you?
4. How do you what God likes and what God does not like?
I hope you will answer so that people can know more about your belief.
