Because I remember asking this question as a child back when I was in Sunday school and my teacher didn't know the answer to it. Now it's been about twenty years and my question still remains unanswered so I was wondering if anybody here could answer it for me. In the book of Samuel there is a guy named Saul and I vaguely remember him changing his name to Paul later on and I do believe that he became an apostle.. Is that the same guy who wrote certain parts of the Bible?
