1 Thessalonians 1:5-6

5For when we brought you the Good News, it was not only with words but also with power, for the Holy Spirit gave you full assurance that what we said was true. And you know of our concern for you from the way we lived when we were with you.

6So you received the message with joy from the Holy Spirit in spite of the severe suffering it brought you. In this way, you imitated both us and the Lord.
