Rest from ministry

Why do we who work in Christian ministry struggle to take proper rest from the work of ministry?

1. I think I don’t need to rest because I’m in Christian ministry. I think somehow that I don't live according to the ordinary laws of God's world i.e. "if you work without rest you will burn out". Perhaps I think the Spirit 'lifts me above' such basic, worldly things.

2. I am driven by an inner emptiness that needs to be filled by achievement and success. Ministry is my idol.

3. I think that God's provision of 24 hours in a day is not enough and that somehow God demands from me time that he has not given me.

4. While I'm superficially reformed, I'm practically arminian and think that everything depends upon me.

5. I like being seen as a martyr by others.
