NVR, I'm with you on this one. Two things come to my mind, one is that there are believers who believe that the Bible is from God. Secondly, believers believe that they have had a personal experience of some kind or another. My conclusion is that it is very hard for the believers to convince you by quoting the Bible or sharing their personal expience with you or me. That leaves blind faith, something that you and I and many others can't accept.
When I wrote to Raymond Franz on the question of the Bible being inspired of God, his bottom line response to me was, it is a matter of faith. He based that on his life experiences.
Utimately, each and every one of us will have to make up our own minds in these matters. Someone else's belief and experiences are theirs alone and they cannot save you.
