I Thessalonians 2:5-7

"For neither at any time did we use flattering words, as you know, nor a cloak for covetousness--God is witness."

"Nor did we seek glory from men, either from you or from others, when we might have made demands as apostles of Christ."

"But we were gentle among you, just as a nursing mother cherishes her own children."

(Words from Paul called the greatest missionary that ever lived, to Thessalonica.)
