2 Corinthians 10:14-16

14We are not overstepping our bounds, as if we had not come to you. Indeed, we were the first to reach you with the gospel of Christ.

15Neither do we boast beyond our limits in the labors of others. But we hope that as your faith increases, our area of influence among you will greatly increase as well, 16so that we can preach the gospel in the regions beyond you. Then we will not be boasting in the work already done in another man’s territory.
