1 Thessalonians 2:3–7
For our appeal does not arise from deceit or ulterior motives or trickery. / Instead, we speak as those approved by God to be entrusted with the gospel, not in order to please men but God, who examines our hearts. / As you know, we never used words of flattery or any pretext for greed. God is our witness!
