Momentum...
Momentum is a powerful thing. By definition it is the force that a moving body has become through a combination of mass and motion. Positive momentum in a church is an "unstoppable force" (as Erwen McManus says). The book of Acts gives us a glimpse into the dynamic that happens when God initiates and people obey - transformation happens! God is at work all around us, and yet it seems that we see so little transformation (relatively speaking). Maybe the problem is our obedience...
