1 Thessalonians 1:4-9

We know, brothers and sisters loved by God, that you are chosen, because our Good News did not come to you in word only, but also in power and in the Ruach ha-Kodesh and with complete certainty—just as you know what kind of men we proved to be while among you for your sake. You also became imitators of us and of the Lord, having accepted the message in much tribulation, with the joy of the Ruach ha-Kodesh. So you became an example to all the believers in Macedonia and Achaia. For the word of the Lord rang out from you—not just in Macedonia and Achaia, but also in every place your faithfulness toward God has gone out, so that we have no need to say anything. For they themselves bring news about what kind of welcome we had among you, and how you turned to God from idols, to serve the living and true God
