My wife and I support a young man who is doing missions work in the Middle East (unofficially) . A few months ago he was sharing one of his experiences with us. He was talking with one of the local college students and turned the subject to faith and asked the student what he knew of Christianity. The students reply was that Christians live in sin because they practice immoral behavior. He added that since the United States is a Christian nation that the country is also immoral. When pressed, the student said Muslims believe this based on what they see in the movies, since most movies come out of the US. Something to think about.
Look at this both ways. How hard do you think it would be to find a Christian in America to say Islam is an evil religion...
