God exists in all mind of people because he truly exist. Its not about being a Christian or any religion but its all about faith. We used to heard several things about them when we are still young and even though we forgot him as times goes by we cant still deny that he still on our unconscious state of mind. I personally experience this one as well when I left my family for college, because I only leaving alone and I really don't have any option but to think about HIM because no one will take care of me during those days. I really feel safe during those times when I think of Him it really helps to remove fear inside of you and you felt that there is something miracle that happening inside you.
