Gandhi had an interesting take on prayer that very much influenced me and led me into "rooms" I never could have imagined. He said that prayer is not for God but for us, so instead of us saying whatever, we should "listen" to what He says, namely through feelings that we either should or shouldn't do something. However, before we act on what we feel, we need to make absolutely certain that it is morally sound first, and if it is, then we should act on it and not find excuses not to.
The above is the single best of theological advice I had ever received from anyone, and I wish I had the time, and you reading it had the interest, to tell you where this all took me over the last three decades.
