Do Not Quench the Spirit
19 Don’t quench the Spirit. 20 Don’t despise prophecies. 21 Test all things, and hold firmly that which is good. 22 Abstain from every form of evil.
Two prohibitions against shutting things down, then two instructions that keep openness from becoming credulity.
Don't quench the Spirit. The verb is used of putting out a fire, so the image assumes something already burning that a person can extinguish. It is a warning about suppression rather than about excess.
Don't despise prophecies. The second prohibition is specific, and it explains the first — the likeliest way to quench the Spirit in that congregation was to treat prophetic speech as an embarrassment. Paul deals with the same instinct at length elsewhere 1 Corinthians 14:39.
But openness alone would be reckless, and the next verse balances it. Test all things — the word for assaying metal — and hold firmly what is good. The testing is commanded rather than permitted, and John gives the same instruction about spirits 1 John 4:1.
The order makes the paragraph work: do not shut it down, and do not swallow it whole. Verse 22 completes it — abstain from every form of evil, so what the testing rejects is dropped entirely rather than held at a distance.
