Passage
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.
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.
2 Thessalonians 3:12 Now them that are such we command and exhort by our Lord Jesus Christ, that with quietness they work, and eat their own bread.
2 Thessalonians 3:13 But ye, brethren, be not weary in well doing.
2 Thessalonians 3:14 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.
2 Thessalonians 3:15 Yet count him not as an enemy, but admonish him as a brother.
2 Thessalonians 3:16 Now the Lord of peace himself give you peace always by all means. The Lord be with you all.
The verse centers on "obey", "word", "epistle", "note", "company", and "ashamed". It is saying that the verse draws attention to "obey" and "word", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "But ye brethren be not weary in..." into verse 15's "Yet count him not as an enemy...", so "obey" and "word" belong inside that flow. In 2 Thessalonians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "obey" and "word" with trust shaped by these words, not by a vague optimism outside the passage.
