I feel very strongly about the threat of Islam to our country so I have to recommend an article by David Wood that answers that very question.

David explains so well how the “religion” of Islam has two faces and we need to be aware of it. He ends the article with the following:
“I’m very happy that most Muslims are willing to live in peace with their neighbors. Yet we have to be honest here. Benevolent Muslims aren’t peaceful because they are following the example set by Muhammad. They are peaceful because they’ve chosen to do what’s right, and because they are willing to live far better lives than Muhammad himself lived. In fact, many Muslims are such kind, peaceful, and gentle people that they seem to be following the example set by another great religious leader—one who died on the cross for the sins of the world and rose from the dead to prove his message. This man gave his listeners a sober warning: “Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves. By their fruit you will recognize them” (Matthew 7:15). And, may I add, we should also watch out for false religions, which come to us crying “Peace! Peace!” when they are built on a foundation of murder and bloodshed.”
More from David can be found on his website Answering Islam.
