Re: "The Power of Prayer"
Great question! This has probably sorta been answered already (sorry had to skim through all the responses for time purposes, plus the time it's taken to write this response) - years ago I heard what I considered to be the best explanation of prayer, specifically the idea that whatever you pray for in Jesus' name will be done - prayer is not so much to get God to do what we want, it's to get us to want what God does. The closer we align ourselves with God, the more we will want what is His best purpose.
Granted it's a tricky thing that's not easily understood, but that's where I stand on the concept :-)
Beat, um, somebody!
