2 Corinthians 10:15-17
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 area 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 another man’s territory.
17 But, “Let him who boasts boast in the Lord.”
