1 Thessalonians 5:16-18
16-18Be cheerful no matter what; pray all the time; thank God no matter what happens. This is the way God wants you who belong to Christ Jesus to live.
19-22Don't suppress the Spirit, and don't stifle those who have a word from the Master. On the other hand, don't be gullible. Check out everything, and keep only what's good. Throw out anything tainted with evil.
