Now in America, there are many claims of evangelism towards the Muslim nations and people. I've listened to the testimonies of these "wannabes" preachers of the Gospel to the Muslim community and have come to one conclusion: That their target was not really Muslim. It's easier or great to call them Muslims for them because preaching to the Muslims is well-known to be the toughest thing to do in the world, and who doesn't want to be known to accomplish a tough job.
However, their approach of "just to show love and friendship" is not going to cut it for the Muslims. They are ignorant of cultures and other religions.
The more believable ones are those testimonies of Muslim converts experiencing some vision of Christ, unfortunately to the Charismatics' liking.
So, the one key I use to determine if it's a cop out:
The foundation of Islam is built on the assumed failure of Judaism and Christianity. Failure to understand this will never result in preaching the Gospel to the Muslims. To a non-Muslim or fake/cultural Muslim, yes, but not to a Muslim, you are not preaching the Gospel to a true Muslim if you fail to understand the basic tenets of Islam, not to mention if you don't even understand Arabic when you call yourself a missionary to the Muslim nations.
Yes, I am trying to make a harsh criticism here, because there are those few who truly bring the Gospel to Muslims, and I will not allow a fool's testimony to tarnish their works.
