2 Corinthians 10:15-18

Nor do we boast and claim credit for the work someone else has done. Instead, we hope that your faith will grow so that the boundaries of our work among you will be extended. Then we will be able to go and preach the Good News in other places far beyond you, where no one else is working. Then there will be no question of our boasting about work done in someone else’s territory. As the Scriptures say, “If you want to boast, boast only about the LORD.” When people commend themselves, it doesn’t count for much. The important thing is for the Lord to commend them.
