More useful points to follow-up my previous post from Kevin DeYoung. As I wrote in that post, these observations are valuable for any pastoral situation. Point 1 is a pearler. From the 9Marks Blog:
Five Ways to Make Sure a Church Turnaround Fails
By Michael McKinley | 9.6.2010There are a lot of churches out there in desperate need of revitalization. Usually, these churches will hire young, inexperienced men to be their pastors (because older, experienced pastors can get better gigs). Here are five mistakes I’ve seen guys make:
1. Pick a fight (or be drawn into a fight) with a well-loved member of the congregation.
2. Make immediate, dramatic changes to the Sunday service (especially the music).
3. Be proud. Act like you know a lot more than the people who have been in that church and in that community for decades.
4. Try to effect good reforms (change church polity, implement meaningful membership, begin to practice church discipline) before you have taught on them and convinced people that they are Biblical.
5. Be impatient. Overspend your pastoral capital. Try to lead people before they trust you and are sure that you love them.
