How we cite our quotes:
Quote #4
See that none of you repays evil for evil, but always seek to do good to one another and to all. (1 Thessalonians 5:15, NRSV)
See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men. (1 Thessalonians 5:15, KJV)
Awww. This is giving us the warm fuzzies. But there's a reason for it: Paul would probably tell you to leave the revenge for God. He's pretty good at it.
Quote #5
Do not quench the Spirit. Do not despise the words of prophets, but test everything; hold fast to what is good; abstain from every form of evil. (1 Thessalonians 5:19-22, NRSV)
Quench not the Spirit. Despise not prophesyings. Prove all things; hold fast that which is good. Abstain from all appearance of evil. (1 Thessalonians 5:19-22, KJV)
This one is a little contradictory: don't try to stop the Spirit of God and the prophets from working, but also test everything. Well, how will the Thessalonians know which stuff is from God and which stuff is evil? Oh, right…Paul will tell them.
Quote #6
This is evidence of the righteous judgment of God, and is intended to make you worthy of the kingdom of God, for which you are also suffering. For it is indeed just of God to repay with affliction those who afflict you, and to give relief to the afflicted as well as to us. (2 Thessalonians 1:5-7, NRSV)
Which is a manifest token of the righteous judgment of God, that ye may be counted worthy of the kingdom of God, for which ye also suffer: Seeing it is a righteous thing with God to recompense tribulation to them that trouble you; And to you who are troubled rest with us. (2 Thessalonians 1:5-7, KJV)
According to Paul, Christians don't need to worry about smacking down all the evil people in the world who are making them suffer. Jesus will do their dirty work for him.
