Ironically, an article I wrote for Answering Islam went up on this very subject just a week prior to Paul's post. In it I argued that the shoe is actually on the other foot, i.e. that Muslims themselves ought to be surprised by what a comparative analysis of the Bible and the Qur'an reveal about this matter.
See for yourself and let me know what you think. And Paul, if you are listening, and if the Lord JESUS wills, of course, perhaps you wouldn't mind telling us what you think after you learn what God's word says on the subject.
(Speaking of Paul Williams and the recent AI update, Sam contributed fourteen replies to Paul, which can all be found in the newly created rebuttal section dedicated just to him: Rebuttals to Paul Bilal Williams.)
