Mainly because it is really easy to listen to people you agree with tell you that everything you are doing is awesome. It is a little harder and frankly a little riskier to go somewhere to be disrupted and challenged and (probably) angered and maybe, just maybe change my mind about something. Marko and I disagree on lots, but we have forged a great friendship primarily by gently pushing each other. Your youth ministry (or marriage or church or life) would be well served for you to get pushed a little bit.
So, how about you join me?
