1 Thessalonians 1:5-7

5 and that our gospel came to you not in word only, but also in power, and in the Holy Spirit, and with much assurance. You know what kind of men we showed ourselves to be among you for your sake.  6 You became imitators of us, and of the Lord, having received the word in much affliction, with joy of the Holy Spirit,  7 so that you became an example to all who believe in Macedonia and in Achaia.
