1 Thessalonians 2:1-4

For you yourselves know, brothers and sisters, that our reception among you was not in vain,

but after we had already suffered and been treated abusively in Philippi, as you know, we had the boldness in our God to speak to you the gospel of God amid much opposition.

For our exhortation does not come from error or impurity or by way of deceit;

but just as we have been approved by God to be entrusted with the gospel, so we speak, not intending to please people, but to please God, who examines our hearts.
