I believe God has heard my prayers. He will make it manifest in His own good time that He has heard me. I have recorded my petitions that when God has answered them, His name will be glorified.
The greatest admission a human can make is that perhaps he does not have the intelligence, the vision, the grasp to fully understand the universe, and that perhaps no human ever will. To put it all down to some omnipotent deity is a cop-out. Factor in fairy tales of an afterlife and it becomes a comforting cop-out.
