How do we know a preacher is sent from God?

To discern if a preacher is sent from God, we can look to the example of John the Baptist. A true preacher will have a clear focus on preaching Jesus Christ and His grace. John was sent to bear witness of the light, not to seek personal gain but to fulfill God's commandment. His sincerity and commitment to the truth, regardless of personal cost, serve as a model for what to seek in modern preachers. If their message revolves around grace and points to Christ as Savior, they are likely sent from God.
