That is a non sequitur. An atheist can, and often does, have more knowledge of the Bible than "Christians." I have already posted the link to the study which showed that to be true.<quoted text>
If a person is an atheist, evidently they have an ignorance of the Bible. They can't comprehend it even if they have read it because they choose not to believe it....
One reason that I am an atheist is that I have studied the Bible, and chose not to believe it (in its entirety).
Your belief in the Bible does not make it any more true.
