The "But where would we go?" question is typical Dub propaganda and Scripture twisting.
Shame on me I said it myself a couple of years ago.
Peter asked"but Lord WHO should we go away to,you have the sayings of everlasting life" (Loose rendition from memory)
So the answer to Dubs is "where to? You could do worse than go to Jesus"
I do agree though that a religion is not necessary,proof of that is first centuary Jewish Christians,they didn't have to leave their religion,they simply put faith in Jesus as the Messiah.
Organized Religions are made by men to dominate men and ALL contain some error. Most Christian faiths contain less error than Jehovah's Witnesses.
