Recently at the Santa Rosa Street Fair we were being heckled by a militant atheist. It's kind of funny because he actually looked like Charles Darwin. Anyway, he was more of a nuisance than anything else, but I could tell that as soon Nate started preaching he was going to be a real problem.
I told Nate, "Let's pray about this guy." Once we bowed in prayer he even started heckling us then: "Oh what a bunch of bull. Do you really think God hears you? What a bunch of superstitious garbage," etc., etc.
We prayed, "Lord, we know that it is your will that your gospel go fourth and this man is proving to be a real distraction. We ask that you would please remove him so that your word may be proclaimed without hindrance."
The Atheist heard every word of the prayer and all he had to do in order to 'prove' that God is a farce was to stay and continue to mock.
Nate started preaching and after about 30 seconds I looked up and saw Mr. Atheist walking across the street, never to be seen again.
Soli Deo Gloria
