Those who know Jesus as Savior and best friend, Muslims who reject his salvation, and all-will you comment?

Shalom, my brother in Christ!! Jesus is my best friend too. Tell your Muslim friend (peace be upon him) that G-d writes scripture through His inspiration. A human writes, whatever book we believe... because he has the physical hands to do it, but G-d's knowledge and understanding for scripture has to come by His Spirit, which is one of supernatural love and humbleness.
