Augustine of Hippo

How much more, therefore, ought men not to claim the credit for themselves if they perform any good work, when the very Son of God in the Gospel said that he sought not his own glory. Nor had he come to do his own will but the will of him who sent him! This will and glory of the Father the apostle now commemorates, that he also, by the example of the Lord who sent him, may indicate that he seeks not his own glory or the performance of his own will in the preaching of the gospel, just as he says a little later, "if I were to please men, I should not be a servant of Christ."
