We don't teach from Books of the Bible because it gets in the way of evangelism. We don't offer different kinds of Bible studies because it gets in the way of evangelism. We don't teach doctrine because it gets in the way of evangelism. If you want to be fed God's word or have the Bible explained to you then you are a fat lazy Christian and you need to shut up and get to work or you need to leave this church because we ONLY do evangelism.
We're so concerned about being polite in society, and rightfully so, that it carries over onto a football team. But on a good football team, they are your friends, but first and foremost they have to be good teammates.
