1 Thessalonians 2:9-12

For you remember our labor and hardship, brothers and sisters. Working night and day so that we would not burden any of you, we preached God’s gospel to you. You are witnesses, and so is God, of how devoutly, righteously, and blamelessly we conducted ourselves with you believers. As you know, like a father with his own children, we encouraged, comforted, and implored each one of you to walk worthy of God, who calls you into his own kingdom and glory.
