Passage
that each of you know how to possess his own vessel in sanctification and honor,
that each of you know how to possess his own vessel in sanctification and honor,
1 Thessalonians 4:2 For you know what commandments we gave you through the Lord Jesus.
1 Thessalonians 4:3 For this is the will of God, your sanctification: that you abstain from sexual immorality;
1 Thessalonians 4:4 that each of you know how to possess his own vessel in sanctification and honor,
1 Thessalonians 4:5 not in lustful passion, like the Gentiles who do not know God;
1 Thessalonians 4:6 and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you.
The verse centers on "each", "possess", "vessel", "sanctification", and "honor". It is saying that the verse draws attention to "each" and "possess", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "For this is the will of God..." into verse 5's "not in lustful passion like the Gentiles...", so "each" and "possess" belong inside that flow. In 1 Thessalonians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "each" and "possess" with trust shaped by these words, not by a vague optimism outside the passage.
