One of the things I appreciate about the T4T (Training for Trainers) approach is how every meeting begins in the first section with reporting in on what you have done the past week to apply what you learned before. Likewise, every meeting ends with the setting of new goals. How are you going to obey and put into practice what you learned in the lesson or story? This accountability loop is a very important part of making obedient disciples.
It goes much further than this though. We must develop an appreciation, even an embracing of friendly accountability in our lives as leaders personally. As we model this, our disciples see it. They begin to value it as well.
