You talk as though prayer is a tool to fix a problem that it has power and if it doesn't work and you don't get what you want then it's useless. Personally I like talking to God. He was the only friend I had when I was DF. For those who will claim I am simply talking to myself that it is soliloquy I offer the following poem
They tell me Lord that when I seem to be in speech with you,Since but one voice is heard, it's all a dream One talker aping two
Sometimes it is, yet not as they conceive it,Rather, I Seek in myself the things I hoped to say But lo!, my wells are dry.
Then, seeing me empty,you forsake The listener's role and through My dumb lips breathe and into utterance wake The thoughts I never knew.
And thus you neither need reply Nor can; thus, while we seem Two talkers, thou art One forever, and I No dreamer,but thy dream
