15. So we do not boast about the work that others have done beyond the limits God set for us. Instead, we hope that your faith may grow and that we may be able to do a much greater work among you, always within the limits that God has set.
16. Then we can preach the Good News in other countries beyond you and shall not have to boast about work already done in someone else's field.
17. But as the scripture says, “Whoever wants to boast must boast about what the Lord has done.”
18. For it is people of whom the Lord thinks well who are really approved, not people who think well of themselves.
