That God can still move and do great things, even if the person or the ministry isn't 100% theologically correct, mature, healthy, etc. (as I see it).
On one hand, this is logical. What person or ministry is ever 100% on? God would have very few people and groups to work with. Plus, the great things he brings about can cause us to grow into greater maturity and learning.
On the other hand, there's a tendency to believe that if God is moving and doing great things, then the person/ministry/group must be right on.
This makes me pause and think of how much I have yet to learn.
