Why do preachers face trials and rejections?

The sermon points out that many of the Lord's most faithful servants, like Paul, experienced significant suffering. These trials serve to remind preachers that their abilities and strength are not sufficient; they must rely solely on God's grace, just as Paul did while imprisoned. His chains did not hinder his ability to preach but rather positioned him to proclaim the gospel in a new context. This teaches that God's purpose often includes using suffering to highlight His power and grace in the lives of His servants.
