1 Thessalonians 2:9-12
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.
10 You are witnesses, and so is God, of how holy, righteous and blameless we were among you who believed.
11 For you know that we dealt with each of you as a father deals with his own children,
12 encouraging, comforting and urging you to live lives worthy of God, who calls you into his kingdom and glory.
