When we are alone, it's easy to think, incorrectly, that we are spiritually advanced. I can watch a Hallmark commercial alone and find myself moved to tears. I tell myself that I am a very compassionate person. But when I spend time in community with a person who annoys me, it's amazing how quickly I experience "compassion fatigue."
In community we discover who we really are and how much transformation we still require. This is why I am irrevocably committed to small groups. Through them we can accomplish our God-entrusted work to transform human beings.
However, experience tells us that simply meeting with a small group does not automatically result in spiritual growth. There are certain practices that must be present, spiritual disciplines that must occur, to facilitate the transforming work of Christ in us. The presence of these things is what makes the difference between all-too-typical small groups, and life-transforming communities of spiritual formation.
