What does the Bible say about the motives of a preacher?

In Paul’s writings, he illustrates that his motive for preaching was to serve the spiritual needs of others rather than to seek any personal advantage or recognition. He questions the Corinthians whether he had committed an offense by abasing himself for their sake, illustrating his willingness to sacrifice his own comfort and reputation for their upliftment (2 Corinthians 11:7). This emphasizes the Reformed principle that true ministry should reflect a servant-hearted attitude, focusing on the gospel and the edification of the church body, rather than being motivated by self-interest or financial gain.
