I think you may have the wrong idea about what prayer is. It is not a bank account that you can go to withdrawal whatever you like. Prayer is a conversation, drawing closer to someone who wants to have a relationship with you. Those of us who do believe in God, and know him, find that our prayers are answered, more and more, the closer we draw to him.Praying will help some people, it consoles them and gives them strength. However, prayers will never be answered because there is no such thing as God. Pray every day to be skinny and beautiful, I guarantee it will not happen.
