I would suggest fellowship meetings of a nature similar to AA meetings. Almost any typical AA meeting naturally includes confession and testimony. It is not a bake sale or potluck or Bible study. Mostly it is about brokenness and the solution. I feel that small, tightlyknit congregations are vital to re-invigorate the church, as practiced in AA. Service to others is heavily emphasized, the primary purpose. We are to be of maximum service to others through a direct and loving relationship with God. 

Being "saved" and knowing Scripture and being seen as a true Christian often act to inhibit honest relationships. Love is the whole purpose of truth. For that love to come forth requires entering into actual relationships with people. For the meetings to work, they must be a "come as you are" gathering. For the meetings to work, there are no experts or quick scripture-fixing. For the meetings to work, they must be heart to heart communication, not doctrine and teaching. Christ gave us a spirit of action, not a system of belief.
