Congregations seeking to transform are willing to move beyond their comfort zone. They are willing to experiment with new ways of doing church. They are willing to risk something that may fail, or that even failed in the past, but they learned from it. They are willing to change something about their schedule, room use, worship style, fellowship events, spiritual formal, missional engagement, etc.
If congregations do not regularly do something that moves them outside their comfort zone, they create a culture that is so comfortable that when essential changes are needed they refuse to move outside of their comfort zone.
