I hate how spiritual formation gets positioned as an optional pursuit for a small special interest group within the church.
A church must grow larger and smaller at the same time. Larger through worship and smaller through small groups.
In all my eleven years of itinerant ministry I cannot recall any growing church which does not encourage small groups
The True Church can never fail. For it is based upon a rock.
T. S. Eliot
Groups break up because they never got across what they wanted to do personally, and they have creative differences, and egos start to clash.
Your God is too Small
