Steve Ray has a list of more than 35 loaded Questions for "Bible Christians" (quotation marks his)(link to the whole list). I originally planned to respond to just 35 of them, but the series seems to have been of interest, so in this extension, I'm responding to three more numbered questions in his list, plus fourteen "bonus questions" that take the form "Where does the Bible say ... ." I'm trying to provide the answers in the same common format as the original series, for easy reference. This is number 1/17.
36) The Koran explicitly claims divine inspiration, but the New Testament books do not. How do you know that the New Testament books are nevertheless inspired, but the Koran is not?
1) The New Testament claims that all Scripture is inspired:
2 Timothy 3:16-17
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, throughly furnished unto all good works.
2) The Koran does not claim to be "inspired" or to have been given by "divine inspiration." It claims to have been directly written essentially from the Creation and simply revealed to Mohamed.
3) We accept the Scriptures on faith, and that faith is reasonable.
4) Faith in the Koran would be unreasonable.
1) We realize that the New Testament wasn't yet complete when 1 Timothy was written. Nevertheless, "all Scripture" was intended to include "all Scripture" and not simply the Old Testament Scripture.
2) It's not simply the fact that Scripture calls it itself inspired that produces our faith.
3) We realize that each individual book of the New Testament may not explicitly state "This book is inspired Scripture" and that consequently a person who wishes to engage in extreme skepticism will always find a reason to doubt. However, such doubt is not reasonable.
