There are ways to evangelize and there are ways to not. I was standing on a corner outside Knot's Berry Farm waiting with a crowd for a light. There were several people there 'evangelizing', dirty, overbearing, rude, and in your face. When one got in my face, I said "Dude! while I agree with everything you are saying here, do you realize just how insane you are making us all look?" He answered with was I embarrassed by hearing the name of Jesus, and I said 'no I am not embarrassed by proclaiming the Name of Jesus, I'm embarrassed by you'. The crowd broke into applause and cheers, and the 'evangelists' backed off as the light finally changed.
The best evangelism shows the life to all, and presents the word to those who seek.
