How do we know true preaching?

True preaching is characterized by its openness and clarity, as Jesus demonstrated by preaching publicly in synagogues and the temple. He spoke boldly and without ambiguity, ensuring that His words were accessible to all (Luke 4:16-22). A preacher who is faithful to God's Word will teach without holding back, emphasizing the Gospel and the nature of God, while consistently affirming the doctrine of Christ, as Paul reminds us in Acts 20:27. True preaching invites people to examine the Scriptures and their content, so they can witness the truth themselves (John 18:21).
