What does the Bible say about the motives of preaching?

In 1 Thessalonians 2, the Apostle Paul illustrates that his preaching was motivated by a desire to please God rather than men. He writes about being entrusted with the gospel and being bold in proclaiming it despite opposition. Paul emphasizes that his motives were holy, just, and unblameable, indicating that true preaching arises from a heart committed to God's glory and the good of His people. The call to witness concerning these motives establishes that the integrity of the preacher is crucial for the efficacy of their message.
