The Bible: Fact, Fiction, or Fable?Josh McDowell
Having faith isn’t enough. Other religions can say that, too.
One of the biggest “heresies” taught today is salvation by faith. We are saved by grace through faith in Christ. We are saved by the grace of God, through faith in Jesus. The value of faith isn’t in the one believing, but the one believed.
Christianity isn’t true because we have faith. It’s true because it’s historical. The question isn’t how valid is your faith, but how valid is the object of your faith. Is Christ who He claimed to be?
“It’s true.” That’s the reason to be a Christian.
Is what we have written down accurate? We analyze the bibliographical evidence for the Bible. The closer in time the copy is to the original, the less chance of error and discrepancy. The fewer time span means fewer copies made, the less chance of human error in copying. The New Testament has the best bibliographical evidence of any other ancient document. The oldest copies (fragments) are within 50 years of the originals. And Josh suggested that new manuscripts that have been found being studied now, we could reduce that gap by 10-15 years. (more here)
