1 Thessalonians 2:4-8

but just as we have been approved by God to be entrusted with the gospel, so we speak, not as pleasing men, but God who examines our hearts. For we never came with flattering speech, as you know, nor with a pretext for greed—God is witness— nor did we seek glory from men, either from you or from others, even though as apostles of Christ we might have asserted our authority. But we proved to be gentle among you, as a nursing mother tenderly cares for her own children. Having so fond an affection for you, we were well-pleased to impart to you not only the gospel of God but also our own lives, because you had become very dear to us.
