1 Thessalonians 2:3-6

Our coming alongside you to encourage you was not out of some delusion, or impure motive, or an intention to mislead you, but we have been approved by God to be those who preach the gospel. So our motivation to preach is not pleasing people but pleasing God, who thoroughly examines our hearts. God is our witness that when we came to encourage you, we never once used cunning compliments as a pretext for greed, nor did we crave the praises of men, whether you or others.
