"Perhaps He has, and you're overlooking Him? Or perhaps part of the way to find Him, is to look for Him. The journey as goal."
Let me tell you first off that I didn't just come to my conclusions about God one day after some bad dream and indigestion. It was a long process of looking and thinking and studying, etc. I've been on that journey and now I am here.
Secondly, if I've overlooked God there should have at least been one other person in all of history who was able to find him. It's too bad that in all those millennia no one has told of a way to conclusively prove the existence of God. Otherwise we wouldn't be having this discussion.
