A friend could offer this Mr. Good some anti smoking gum, pills or a tobacco substitute. This does work. If enough members did it this could it be effective. Some churches will not accept those that don't comply with a minimum standard. Members should confess serious wrongdoing to there pastor and seek help.
Voluntary confession is usually a sign that the member is beginning the process of repentance.
If a voluntary confession covers a serious transgression committed in the past and the member's conduct in the intervening years demonstrates full repentance the transgression should be ignored. The church judicial system should be a means to help people repent and stay in the church instead of getting rid of them. Under very difficult and unmanageable circumstances it is advisable to remove the transgressor from the church membership records. The way back made easier by loving and caring friends. This repentance should be confidential between caring friends and the pastor.
