From The Archer and the Arrow:

1. Preachers are absolutists in an age of relativism
2. Preachers call for repentance
3. Preachers risk offending the powerful
4. Popular prophets are either dead or foreigners
5. People want to catch us out
6. Preachers risk being misunderstood
7. Preachers avoid balance
