1 Thessalonians 1:5-6; 1 Thessalonians 2:2; 1 Thessalonians 2:17

5 For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake. 6 And ye became followers of us, and of the Lord, having received the word in much affliction, with joy of the Holy Ghost:
2 But even after that we had suffered before , and were shamefully entreated , as ye know , at Philippi, we were bold in our God to speak unto you the gospel of God with much contention.
17 But we, brethren, being taken from you for a short time in presence, not in heart, endeavoured the more abundantly to see your face with great desire.
