A simple question.
If the Muslims don't even believe that Jesus is the Son of God then WHY take it the step UP from there and say that he is God for?
Please read this slowly and try to become a muslim yourself, as Paul says we are suppose to do, if we really want to reach them. The Muslims are no different then the Religious Jews that Jesus was dealing with in the New Testament. I don't recall Jesus spending hours with people explaining the concept of the trinity to them because there are a LOT of baby steps to be taken before they ever get to that point of spiritual understanding.
