I dunno I've seen lots of freepers claim to have proofs of the existence of God.
The interesting thing would be to prove that God conforms to the beliefs of any particular church or denomination. Nailing down exactly which church has it right -- that would be interesting.
Personally I belong to the church of the seven blind men. None of us has the whole picture.
Nah, that's the easy part. Supposing you believe the Bible to be the word of God; forget 99% of what you've heard from various pulpits and read the book of Acts for a description of the Lord's church. Find a group of believers that conform to those standards and worship in that manner. Voila!.
As usual, you've got it backwards. It's not that God has to conform to our beliefs, but that we conform to God's.
