2 Corinthians 10:14-16 New International Version - UK (NIVUK)
14 We are not going too far in our boasting, as would be the case if we had not come to you, for we did get as far as you with the gospel of Christ. 15 Neither do we go beyond our limits by boasting of work done by others. Our hope is that, as your faith continues to grow, our sphere of activity among you will greatly expand, 16 so that we can preach the gospel in the regions beyond you. For we do not want to boast about work already done in someone else’s territory.
