The First Epistle to the Thessalonians, commonly referred to as First Thessalonians or 1 Thessalonians, is a Pauline epistle of the New Testament of the Christian Bible. The epistle is attributed to Paul the Apostle, and is addressed to the church in Thessalonica, in modern-day Greece. It is likely the first of Paul's letters, probably written by the end of AD 52.
We are not trying to please people but God, who tests our hearts. You know we never used flattery, nor did we put on a mask to cover up greed—God is our witness. We were not looking for praise from people, not from you or anyone else, even though as apostles of Christ we could have asserted our authority. Instead, we were like young children among you.
Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord. Therefore encourage one another with these words.
4:17-18 (English Standard Version)
Be at peace among yourselves. Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men. See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men. Rejoice evermore. Pray without ceasing. In every thing give thanks: for this is the will of God in Christ Jesus concerning you. Quench not the Spirit. Despise not prophesyings. Prove all things; hold fast that which is good. Abstain from all appearance of evil.
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.
Live in peace with each other. And we urge you, brothers and sisters, warn those who are idle and disruptive, encourage the disheartened, help the weak, be patient with everyone. Make sure that nobody pays back wrong for wrong, but always strive to do what is good for each other and for everyone else. Rejoice always, pray continually, give thanks in all circumstances; for this is God’s will for you in Christ Jesus. Do not quench the Spirit. Do not treat prophecies with contempt but test them all; hold on to what is good, reject every kind of evil.
