Here's an article by Andy Davis that speaks of the "Dangers in Reforming a Church".
http://timmybrister.com/2008/06/24/nfc-ii-andy-davis-on-dangers-in-reforming-a-church/It's helpful for me to know that although there are issues that are exclusively related to GCx, some of the things that folks may have issues with may be common in other churches as well.
Here's what Andy Davis writes:
1. Forgetting the centrality of God in church reform
2. Self-reliance
3. Failure to rely on the Word alone
4.Deficiency in prayer or prayerlessness.
5. Pride toward your people resulting in gossip and slander about you.
6. Cowardice or fear of man
7.Mistaking non-essentials for essentials
8. Impatience
9. Discouragement
10.Not developing men as leaders around you.
Then Davis puts the "Ten Dangers Turned Positive"
1. Keep the glory of God central in all things.
2. Rely on God and God alone.
3. Unleash the power of the word of God through faithful exposition of Scripture.
4. Saturate your efforts through prevailing prayer.
5. Humble yourself continually before God and others; see the grace of God in your own life.
6. Be strong and courageous, fearing God more than men.
7. Keep clear on essential issues; spend your strength on them.
8. Be patient. Don’t expect reformation to come overnight.
9. Never be discouraged; Christ will most certainly build his church.
10. Build a strong group of godly men in your church who will encourage you in the work of reformation.
