I happened upon a street evangelism scene at the beach the other day.
Having been required to do this exercise for a college class (and otherwise), I was especially curious to observe the technique. An earnest woman in her 20s was painting on butcher paper a version of what appeared to be a "Campus Crusade for Christ" (CCC) tract. The audience was comprised of a handful of middle-aged folks and a rowdy group of teenage girls, who were smoking and making rude comments. I immediately felt empathy for the speaker.
At the conclusion of the presentation, the speaker asked if people would be interested in accepting Christ and offered written materials. Except for the obstreperous smokers who stormed off mid-speech, the "audience" turned out to be plants who were holding tracts about how to receive God's forgiveness (not a CCC publication). One was pressed into my hand.
While it's easy to criticize, I want to emphasize that the motivations appeared pure. It's not easy to do what they were doing, and I'm confident they were doing this out of a genuine concern for others.
However, when I read the tract, I was struck by its works-orientation. Immediately following quotations of verses from 1 John about believing in the Son of God for eternal life (1 John 5:12-13), there were no fewer than five commands to do things (other than believing or having faith) evidently tied to receiving God's forgiveness.
Works-righteousness is our "default setting", as written about in Michael Horton's Christless Christianity (reviewed here on January 15, 2009, and also written about on November 23, 2009). We can't help ourselves, unless we grasp what the Gospel really is. Only when we do that can we truly recognize how revolutionary and counterintuitive it actually is.
