NOT Evangelism

On Monday, my coworker told me about a conversation he had with a man at a flea market over the weekend. The man put a tract in his hand, asked him if he had ever disagreed with his parents, and told him he was going to hell because he had violated one of the commandments. My coworker is Muslim and politely told the guy that he did not agree and after a few more minutes of conversation, left. I have shortened the story intentionally, because I don't want to focus on the story, but on the method.

I don't even know where to begin with this. This "evangelist", for lack of a better term, makes me sick. How can one even think that approaching someone and telling them they are going to hell will change a lifetime of beliefs? If one's beliefs are swayed so easily, I might question the certainty of one's belief. I'd like to go over the absurdity of this approach.

Being in violation of God's law, in the example of disagreeing with parents, means that you are going to hell and therefore in need of Christ.

1. Who said I believe in God?
2. Who said disagreeing with parents was wrong?
3. Why should I accept the Bible as an authoritative source of truth for me?
4. On what basis do you state that hell exists? See question 3 when you respond.
5. If I did believe hell exists, why is Christ the only way?
6. You are stating things that you believe to be true--and I disagree with your beliefs--why do you think you are right and I am wrong?
7. I believe in X (for a Muslim it would be Allah, who is believed to be the same God as the Jewish and Christian God); why am I wrong?
8. Who is to say that what you claim is God's law is actually God's law? My religious books say otherwise.

Frankly, I am embarrassed by this guy's approach to sharing the gospel. It makes me think of the times when I so firmly believe something and passionately try to tell others, only to find them not as receptive to what I firmly believe is true. Perhaps telling people what we believe isn't a very effective way of communicating our beliefs, especially in the context of not knowing the person. I am finding that the older I get, the less I really ought to talk and the more I really ought to listen. And I am really bad about both.
