Whether the family goes on a spiritual basis or not, the alcoholic member has to if he would recover. The others must be convinced of his new status beyond the shadow of a doubt. Seeing is believing to most families who have lived with a drinker.
We are not cured of alcoholism. What we have is a daily reprieve contingent on the maintenance of our spiritual condition. Every day is a day when we must carry the vision of God's will into all of our daily activities.
