Passage
But *ye*, brethren, do not faint in well-doing.
But *ye*, brethren, do not faint in well-doing.
2 Thessalonians 3:11 For we hear that [there are] some walking among you disorderly, not working at all, but busybodies.
2 Thessalonians 3:12 Now such we enjoin and exhort in [the] Lord Jesus Christ, that working quietly they eat their own bread.
2 Thessalonians 3:13 But *ye*, brethren, do not faint in well-doing.
2 Thessalonians 3:14 But if any one obey not our word by the letter, mark that man, and do not keep company with him, that he may be ashamed of himself;
2 Thessalonians 3:15 and do not esteem him as an enemy, but admonish [him] as a brother.
The verse centers on "brethren", "faint", and "well-doing". It is saying that the verse draws attention to "brethren" and "faint", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "Now such we enjoin and exhort in..." into verse 14's "But if any one obey not our...", so "brethren" and "faint" 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 "brethren" and "faint" with trust shaped by these words, not by a vague optimism outside the passage.
