There have been any number of Christian leaders who have fallen recently, and while the publicity makes it appear that there are more and more, I suspect this isn’t anything new.
One major reason for a failure in leadership is that we put too much trust in people. We give a pastor a great deal of authority, we give him a job that is impossible for any one person to do, and then we’re surprised when failure occurs. I think the pattern of Christian leadership is not supposed to put that much pressure or authority on any single person.
I believe that reasonable responsibility, reasonable trust, and a reasonable job load would be a good starting point to helping Christian leaders keep their balance.
