For me, personally, the experience was a step backward on my walk toward Christ. It wasn't until much later that a few people I'd grown to trust patiently drew me into the mystery.
As sincere as he was, that preacher misunderstood the nature of the mission. People are suspicious and hurting. The world has robbed most of us of our ability to trust. It takes time to gain it back. Maybe there's a place for "street corner evangelization" (anyone who's heard of Frank Sheed knows there's at least one man who did it well), but most of us are in this for the long haul. Evangelization is a process. And it begins with relationships. That seething student may have been an attentive listener in another, more properly cultivated context.
