“For you yourselves know, brethren, that our coming to you was not in vain. But even after we had suffered before and were spitefully treated at Philippi, as you know, we were bold in our God to speak to you the gospel of God in much conflict. For our exhortation did not come from deceit or uncleanness, nor was it in guile. But as we have been approved by God to be entrusted with the gospel, even so we speak, not as pleasing men, but God who tests our hearts.” 1 Thessalonians 2:1-4.
