Jesus is our model. Among many examples in the gospel record is John's account of Jesus encounter with a Samaritan woman, initiated not by a pronouncement of her guilt but by his asking her for a drink. This was an act the exclusive religious leaders of his time wouldn't think of doing. Therefore confess your sins to each other and pray for each other so that you may be healed. Unfortunately, many if not most of our congregations are not healing communities but places where we all pretend that we are good, so we dare not reveal our brokenness for fear of rejection.
Many alcoholics testify to feeling unwelcome in their congregation after their problem became known.
One example of healing community is Alcoholics Anonymous, widely regarded as the most successful treatment program for addiction. AA is a community of persons who recognize that their lives are out of control due to alcohol addiction. The participants understand and accept each other because they have experienced the problem themselves. Similar models being used for a wide variety of personal problems have spread around the world. We might well ask why it is necessary to become an alcoholic in order to belong to such a group.
