How do you know that the bible was inspired by the Almighty God? Did He personally come down, tap you on the shoulder and say, "hey, that's my book there!"?
Odds are that He didn't, which means you believe like the rest of us. You believe by faith! Now, could it be possible that a Muslim draws his convictions on the Qu'ran the same way we do the bible?
What if a Muslim states that his book is inspired and the bible was a "satanic masterpiece of evil," how would you react?
You see, the book isn't the problem. It is the heart of men associated with these books to do harm for that purpose. Jesus told us that the bible does NOT (in my Maury Povich voice) contain within it's pages eternal life.
And if the book I believe and have faith in does not contain it, then I'm sure that the Qu'ran does not as well.
