2 Corinthians 10:14-15

We are not overstepping the limits of our province, as if we did not [legitimately] reach to you, for we were the [very] first to come even as far as you with the good news of Christ. We do not go beyond our proper limit, boasting in the work of other men, but we have the hope that as your faith [in Christ and His divine power] continues to grow, our field among you may be greatly expanded [but still within the limits of our commission]
