Paul instructs the Thessalonians to discipline believers who do not behave in a manner worthy of the kingdom. He writes, "Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walks disorderly", (2 Thessalonians 3:6) that "if any would not work, neither should he eat" (3:10) and "if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed" (3:14).
These are not easily followed instructions because of two pitfalls. If we correct out of an arrogant heart, we are in danger of falling into temptation ourselves (2 Thessalonians 3:15; Galatians 6:1). Secondly we have trouble following through when the violators are our friends.
Jesus gives us specific instructions on how to correct (Matthew 18:15-17). First we are to approach the matter privately. Next we are to take one or two people with us to approach them. Finally we are to bring it to the entire body of believers. All of this is done to rescue the fellow believer from his sin and must be done with a heart the recognizes our own vulnerability to transgress.
Paul warns against arrogance saying, "Yet count him not as an enemy, but admonish him as a brother" (2 Thessalonians 3:15).
