I Thessalonians 2:4-8

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. 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. So, affectionately longing for you, we were well pleased to impart to you not only the gospel of God, but also our own lives, because you had become dear to us.
