2 Corinthians 10:13-15
10:13 But we will not boast beyond certain limits, but will confine our boasting according to the limits of the work to which God has appointed us, that reaches even as far as you.
10:14 For we were not overextending ourselves, as though we did not reach as far as you, because we were the first to reach as far as you with the gospel about Christ.
10:15 Nor do we boast beyond certain limits in the work done by others, but we hope that as your faith continues to grow, our work may be greatly expanded among you according to our limits,
