Paul writes with Silvanus and Timothy to the church of the Thessalonians, which is in God the Father and the Lord Jesus Christ, and greets them with grace and peace. He says they always thank God for all of them and remember them in prayer, thinking of three things God has produced in them: their work of faith, their labor of love and their steadfastness of hope in our Lord Jesus Christ.
Paul knows that God loves them and chose them, because the gospel did not come to them in word only but with power, with the Holy Spirit and with full conviction. He also reminds them of how he and his companions lived among them. In turn the Thessalonians became imitators of the missionaries and of the Lord: they received the word with the joy of the Holy Spirit, even in much affliction.
As a result they became an example to all the believers in Macedonia and Achaia. The word of the Lord rang out from them, and their faith in God is known everywhere, so that Paul does not even need to speak of it. Others report how the missionaries were received and how the Thessalonians turned from idols to God, to serve the living and true God and to wait for his Son from heaven, whom he raised from the dead, Jesus, who delivers us from the wrath to come.
