Passage
so, then, brethren, stand ye fast, and hold the deliverances that ye were taught, whether through word, whether through our letter;
so, then, brethren, stand ye fast, and hold the deliverances that ye were taught, whether through word, whether through our letter;
2 Thessalonians 2:13 And we--we ought to give thanks to God always for you, brethren, beloved by the Lord, that God did choose you from the beginning to salvation, in sanctification of the Spirit, and belief of the truth,
2 Thessalonians 2:14 to which He did call you through our good news, to the acquiring of the glory of our Lord Jesus Christ;
2 Thessalonians 2:15 so, then, brethren, stand ye fast, and hold the deliverances that ye were taught, whether through word, whether through our letter;
2 Thessalonians 2:16 and may our Lord Jesus Christ himself, and our God and Father, who did love us, and did give comfort age-during, and good hope in grace,
2 Thessalonians 2:17 comfort your hearts, and establish you in every good word and work.
The verse centers on "brethren", "stand", "fast", "hold", "deliverances", "taught", "whether", and "through". It is saying that the verse draws attention to "brethren" and "stand", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "to which He did call you through..." into verse 16's "and may our Lord Jesus Christ himself...", so "brethren" and "stand" 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 "stand" with trust shaped by these words, not by a vague optimism outside the passage.
