Let me start by pointing out that Islam, Judaism and Christianity are all monotheistic religions of the same god. Call him Allah, Yahweh or Jehovah he is the same god. Something that most Christians do not know and do not want to know is that Muslims worship the same god, read the same Bible; Old and New Testament and they also believe in Jesus Christ. They, like the Jews just don’t believe he was the son of god, Islam does however see him as a prophet of god. They also differ from Christians on the Resurrection as they believe that god ascended Jesus into heaven before he died on the cross. They all three believe they are descendants of Adam, of Abraham and of Noah.
Another not well know fact and also a commonly disputed fact; as much so as their god being the same god and their holy books being the same is that Muslims claim the Quran was given to Muhhamed by the Arch Angel Gabriel. Yes that Arch Angel Gabriel.
What does all this have to do with terrorism? Just as Christians can’t all be lumped in the same group as Jim Jones, Davis Koresh, Adolf Hitler or those that took part in the Inquisitions or the Crusades, not all Muslims can be lumped in the same groups as terrorists; ISIS, Al Queda or Boko Haram.
