open-air

I have a Reformed friend from church who travels to Chicago every Saturday to engage in evangelism. However, I was not particularly happy with what I saw when I went with him. As we were moving to a different destination inside a subway train, he used his megaphone and began to preach repentance...

The topic has come up on Puritan Board now and then about whether open-air preaching is appropriate/helpful. Phil Johnson has a post on this that I appreciated. I hope some of you do too. Pyromaniacs: Street-Preaching
