Does prayer change the outcome of things? I mean, if it's God's will, why would a prayer change anything if it's already written down?
I am free to do as I wish: I can go crash my car if I want to. There's nothing stopping me, except if I fall down the stairs or can't find my keys; pretty random stuff, you know? But there lies God's hand, blessed randomness: if something would happen on this Earth by his will, it won't happen by a big ass hand coming down from the sky and stealing my keys, he has to work through already existing in this world (like a programmer, using other programs or circuitry to interact with the operating system).
He built you, he knows you, and prayer is a two way communication. Prayer is not going to change the world to do your bidding (and nothing's written yet), but it's going to change YOU to do your bidding, and that does change the outcome of things. It's not God will the one that changes through prayer (he wants you to do good, period, he doesn't concern himself with mortal problems), it's your will that changes.
