1 Thessalonians 2:1-4

For you know, brothers and sisters, that our coming to you has not been ineffective (fruitless, in vain), but after we had already suffered and been outrageously treated in Philippi, as you know, yet in [the strength of] our God we summoned the courage to proclaim boldly to you the good news of God [regarding salvation] amid great opposition. For our appeal does not come from delusion or impure motives, nor [is it motivated] by deceit [our message is complete, accurate, and based on the truth—it does not change]. But just as we have been approved by God to be entrusted with the gospel [that tells the good news of salvation through faith in Christ], so we speak, not as [if we were trying] to please people [to gain power and popularity], but to please God who examines our hearts [expecting our best].
