You know how church conflict usually works. The 3rd Grade Sunday School teacher gets mad at the Superintendent and tells her best friend about it, who happens to be the head of the board of Deacons. Then the Deacon, much to the surprise of the pastor, says at the end of the Deacons meeting, "I think we have a problem with the Sunday School Superintendent."  Soon the whole church is talking about it, except the people who are actually upset with each other -- and who after a day or two would have let bygones be bygones. This creates patterns in the church and soon the pastor is spending more time smoothing ruffled feathers and trying to get everyone to get along than in preparing sermons or reaching out to new people.

Conflict saps the life out of the church.  Pastors that want to survive learn to tell people to talk to the person they are angry with first, then come back if they can't work it out.  I'm sure Jesus had to do this all the time with an unruly group of fishermen, a tax collector, a zealot and two brothers known as the Sons of Thunder.  There may have been days when he felt like he would be better off without disciples, but his whole purpose was to create a community of believers, not just individuals interested in spirituality.
