1 Thessalonians 2:9-13 New Revised Standard Version (NRSV)
9 You remember our labor and toil, brothers and sisters;[a] we worked night and day, so that we might not burden any of you while we proclaimed to you the gospel of God. 10 You are witnesses, and God also, how pure, upright, and blameless our conduct was toward you believers. 11 As you know, we dealt with each one of you like a father with his children, 12 urging and encouraging you and pleading that you lead a life worthy of God, who calls you into his own kingdom and glory.
13 We also constantly give thanks to God for this, that when you received the word of God that you heard from us, you accepted it not as a human word but as what it really is, God’s word, which is also at work in you believers.
1 Thessalonians 2:9-13 New International Version (NIV)
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.
13 And we also thank God continually because, when you received the word of God, which you heard from us, you accepted it not as a human word, but as it actually is, the word of God, which is indeed at work in you who believe.
