1 Thessalonians 1:3; 1 Thessalonians 2:9; 1 Thessalonians 3:5

1 Thessalonians 1:3

3 We remember before our God and Father your work produced by faith, your labor prompted by love, and your endurance inspired by hope in our Lord Jesus Christ.

1 Thessalonians 2:9

9 Surely you remember, brothers and sisters, our toil and hardship; we worked night and day in order not to be a burden to anyone while we preached the gospel of God to you.

1 Thessalonians 3:5

5 For this reason, when I could stand it no longer, I sent to find out about your faith. I was afraid that in some way the tempter had tempted you and that our labors might have been in vain.
