One of the most powerful tools of formation is the small group. In such groups, people seek the formation and transformation of other people. Transformation - seeking new lives and behavior - is what they are all about.
The church in a new time has a lot to learn from small groups. In this era, a kind of bland and generalized friendliness seemed adequate for many. But today people seek, and formation requires, something more intentional, something with a greater depth of intimacy and honesty, in which people are held accountable for their actions.
