1 Thessalonians 2:4-6

but just as we have been approved by God to be entrusted with the gospel, so we speak, not to please man, but to please God who tests our hearts. For we never came with words of flattery, as you know, nor with a pretext for greed—God is witness. Nor did we seek glory from people, whether from you or from others, though we could have made demands as apostles of Christ.
