Did you ever doubt the bible? But now accept it as being infallible?

Sort of. I would not say that I thought that the whole bible was infallible because it clearly has many errors due to lack of knowledge of the writers as well as contradictions. I did however investigate the prophecy claims and when I read Isaiah 52 and 53 it really sounded a lot like Jesus. It was describing a servant of God. I eventually read the whole bible and when I read all of Isaiah it became clear that the servant was the Hebrews of Judea. It referred to the entire country as a servant to God. Later I discovered that the NT writers used the OT as a source for their stories. That is why so many things sound like they're describing Jesus in the OT, but when you read the full context discover that it's not. So I came close to believing there was something to the christian claims, but now I have a much better understanding of the bible and remain an atheist.
