To put things into perspective, i go to a coptic orthodox school, and one of the priests has this way of getting the kids closer to God. He says that if you pray a lot and get closer to God, he will guide you direct your path and guide you to success, i.e. getting in the university course which you want (which is mostly medicine in my school). I know that we build a close relationship with God to be united with him in Heaven when we die and to have a higher power in whom we can trust to aid us. But my friend (who isn't quite close to God) asked me "Why do we need God? It's not to be successful, i know i alot of people who are successful, top surgeons and businessmen, who are in-fact atheist. They also have families and are very happy. All they did was work hard, so if i work hard i can be successful". I didn't know how to reply to him, as he sort of has a more materialistic approach towards things.
