Some will read what Hafemann says and conclude that suffering = spirituality (even though he warns that is not the case). Their achievement-oriented personality will push them to work harder (hence suffer more) in order to feel good about their relationship with God.
The result will be what Mark Driscoll blogged about a couple of months ago: Death by Ministry. The statistics are frightening, such as:
Fifteen hundred pastors leave the ministry each month due to moral failure, spiritual burnout, or contention in their churches.I don't have it figured out - how you do ministry by "death" without becoming a victim of death by ministry.
Perhaps part of it is knowing the warning signs of burnout. Driscoll mentions quite a few. I've also found these from a blogger named Rev Sam:
When pastors are under stress, they lose things in the following order:
1st Their wider reading;
2nd Their prayer life;
3rd Their sense of humour;
4th Their humanity.
Driscoll offers several insights on how to prevent "dying a death by ministry." I would add that a huge part of it is being a servant of Christ first, and then a servant of others. In other words, if my relationship with God flows out of my ministry to people, I'm headed to disaster. I have to keep guarding my heart, and making sure that my ministry flows out of my relationship with Christ.
