For our gospel did not come to you in word only, but also in power, in the Holy Spirit, and with much assurance. You know what kind of men we were among you for your benefit,
and you became imitators of us and of the Lord when, in spite of severe persecution, you welcomed the message with the joy from the Holy Spirit.
As a result, you became an example to all the believers in Macedonia and Achaia.
For the Lord's message rang out from you, not only in Macedonia and Achaia, but in every place that your faith in God has gone out, so we don't need to say anything.
References for 1 Thessalonians 1:8
For they themselves report about us what kind of reception we had from you: how you turned to God from idols to serve the living and true God,
and to wait for His Son from heaven, whom He raised from the dead-Jesus, who rescues us from the coming wrath.
