“For we hear that there are some which walk among you disorderly, working not at all, but are busybodies. Now them that are such we command and exhort by our Lord Jesus Christ, that with quietness they work, and eat their own bread. But ye, brethren, be not weary in well doing. 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. Yet count him not as an enemy, but admonish him as a brother.” 2 Thessalonians 3:11-15 (KJV)
Those who do not work are some of the disorderly. This is of course speaking of able-bodied people who can work but will not do so. They are meddlesome, mischievous rascals who need to be dealt with for the good of the Church, and for their own well being.
Of course in the day which we live people are dependent more upon government welfare, and food stamps services; even professing Christians. It should still be the case, even the law of creation tells us that if you do not work you will not eat. Work is not a curse, but a blessing that benefits the worker, his family, the society he/she lives in.
“…Be not weary in well doing” is an encouragement to those who work to keep on working. Whatever honest work you are doing keep on doing it, and do it as to the Lord (Ephesians 6:5-8). That is right work as if you are doing it for the Lord; because you are, if it is in a work that is pleasing and honoring to His name.
If any will not hear the Word, we are told “Not to keep company” with them so that they will be shamed. He is speaking of saved people, because he says, “Do not count him as an enemy, but… as a brother.”
