Jesus did not come with a lot of theology. He did not start a Bible school.
He said: Come and follow me. He called apprentices (disciples), who had to learn through his example ... If we are going to be effective in making disciples, like he calls us, we must then do it the same way as he did. We need to stop teaching so much, which just gives us knowledge, but not much to obey'. See this challenging teaching that will help you to understand what Jesus called us to.
