1 Corinthians 9:16

Verse 16. It is no glory. That is, I have nothing to glory of. Challoner.—If I preach the gospel through compulsion, fear, or mere necessity, having no other means of maintenance, I must not look for a reward in heaven; but now doing it through charity and freely, I shall have my reward from God; and the more abundant the charity, the greater the reward. Saint Augustine de Op. Mor. i. 5.
