But the bottom line is.... he won't save any. God will save those that God has chosen. I don't buy the idea that we have to be in bars or those people will NEVER hear the gospel.
Of course everyone who is saved in the end is saved by God. But I don't see how the potential for misguiding people is increased in a bar versus a streetcorner or a church for that matter. There are lots of wrongheaded preachers out there, and they will misguide people whereever they go. The good ones wont, even in bars and sewers.
