When people stop attending meetings and going in the d2d, they are unofficially marked as dangerous association. Thus only elders or rank and file deemed strong enough may be sent to "encourage" the person. But as in marking no socializing, no inviting them over for dinner, no including them in parties or "get-togethers." Unless the start going to the meetings, they are not going to be "rewarded" by bad behavior. They think if you can do those things you can go to the meetings.

We have been counseled to be cautious in our dealings with men of the nations, unbelievers, and ordinary persons. (See the November 15, 1988, issue of TheWatchtower, pages 15-16.) Why should we have unnecessary social contact with people who still pursue worldly ways and who have not become worshipers of Jehovah? (2 Cor. 6:14, 15) Some who are negligent spiritually may seek out others who also hold on to worldly thinking and ways instead of seeking association with mature Christians who could help them become strong in the faith. They fail to appreciate that attendance at social gatherings with worldly, unprincipled people can weaken their faith and corrupt them.—Compare 2 Thessalonians 3:14, 15.

*In what sense would they "withdraw" from him? Evidently, this was in a social context. (Compare Galatians 2:12.) Their ceasing to have social dealings and recreation with him might show him that principled people disliked his ways. Even if he did not get ashamed and change, at least others would be less likely to learn his ways and become like him. At the same time, these individual Christians should concentrate on the positive. Paul advised them: "For your part, brothers, do not give up in doing right."—2 Thessalonians 3:13.
