Passage
Try all things, and keepe that which is good.
Try all things, and keepe that which is good.
1 Thessalonians 5:19 Quench not the Spirit.
1 Thessalonians 5:20 Despise not prophecying.
1 Thessalonians 5:21 Try all things, and keepe that which is good.
1 Thessalonians 5:22 Absteine from all appearance of euill.
1 Thessalonians 5:23 Nowe the very God of peace sanctifie you throughout: and I pray God that your whole spirite and soule and body, may be kept blamelesse vnto the comming of our Lord Iesus Christ.
The verse centers on "all things", "keepe", and "good". It is saying that the verse draws attention to "all things" and "keepe", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "Despise not prophecying..." into verse 22's "Absteine from all appearance of euill...", so "all things" and "keepe" 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 "all things" and "keepe" with trust shaped by these words, not by a vague optimism outside the passage.
