I think chapter 5 is my favorite chapter in 1 Thessalonians, but my favorite verses are:
16 Always be joyful. 17 Never stop praying. 18 Be thankful in all circumstances, for this is God’s will for you who belong to Christ Jesus.
19 Do not stifle the Holy Spirit. 20 Do not scoff at prophecies, 21 but test everything that is said. Hold on to what is good. 22 Stay away from every kind of evil.
I like the way The Voice translates this section as well:
Celebrate always, pray constantly and give thanks to God no matter what circumstances you find yourself in. (This is God's will for all of you in Jesus the Anointed). Don't suppress the Spirit. Don't downplay prophecies. Take a close look at everything, test it, then cling to what is good. Put away every form of evil.
I LOVE Celebrate Always!
