Prayer, for me, is a way to communicate with God. It helps me deal with problems, and puts confusing things into perspective. Praying also allows me to get things off my chest that I might not be able to trust any of my friends here on earth with, and it gives me the chance to thank God for all He's done for me in the past, present, and all He's going to do for me in the future! Also, it's usually when I get the best sense of whether or not the path I'm on, or the decision I'm thinking of making, is according to His will.
