1 Thessalonians 5:21 (5:12-22)
“Test all things. Hold fast to what is good.”

This verse calls believers to discernment and steadfastness. We are to examine everything carefully and cling to what is good, true, and aligned with God’s Word.
Never Read a Bible Verse
— 1 Thessalonians 5:12-22 NKJV
For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ, who died for us, that whether we wake or sleep, we should live together with Him. Therefore comfort each other and edify one another, just as you also are doing.
And we urge you, brethren, to recognize those who labor among you, and are over you in the Lord and admonish you, and to esteem them very highly in love for their work’s sake. Be at peace among yourselves.
Now we exhort you, brethren, warn those who are unruly, comfort the fainthearted, uphold the weak, be patient with all. See that no one renders evil for evil to anyone, but always pursue what is good both for yourselves and for all.
Rejoice always, pray without ceasing, in everything give thanks; for this is the will of God in Christ Jesus for you.
Do not quench the Spirit. Do not despise prophecies. Test all things; hold fast what is good. Abstain from every form of evil.
Important Context and Discernment
Paul is not giving a blank check to every claim of “thus saith the Lord.” Right after telling them not to despise prophecies, he immediately says “Test all things.” True prophecy must be weighed carefully against Scripture and must point people to Christ, not away from Him.
Any so-called prophecy or modern “prophet” that adds new doctrines, changes the gospel, or leads people to another Jesus fails this test.
Mainstream Understanding
The command was given to the early church, before the New Testament was completed. Some believers were tempted to reject or look down on prophetic messages because there were also false prophets and because some genuine prophecies may have been uncomfortable or hard to understand.
Paul’s point is not “accept every claim of ‘God told me’ without question.” Right after this verse he says:
“Test all things; hold fast what is good.” (v. 21)
Key Commentary Points
- John MacArthur: “Do not despise prophetic utterances” means do not look down on or reject the revelation of God (whether spoken or written). But it must always be tested. He stresses that in the completed canon, we test everything against Scripture.
- GotQuestions / Ligonier / Reformed sources: The gift of prophecy in the early church was real, but it was never meant to be above scrutiny. True prophecy will never contradict Scripture and will point people to Christ. The command is balanced by the command to test everything.
- Common application today: This verse is often misused by groups that claim ongoing, authoritative revelation (new scriptures, modern prophets, etc.). The biblical response is: Test it. If it adds to, subtracts from, or changes the finished work of Christ, it fails the test.
