2 Corinthians 10:14-16

14For we are not overextending ourselves (as though our authority did not extend to you), for it was to you that we came with the gospel of Christ;

15not boasting of things beyond measure, that is, in other men’s labors, but having hope, that as your faith is increased, we shall be greatly enlarged by you in our sphere,

16to preach the gospel in the regions beyond you, and not to boast in another man’s sphere of accomplishment.
