How does the preaching of the Word relate to the authority of Christ?

The preaching of the Word is directly tied to the authority of Christ, who is the ultimate Prophet and Shepherd. In Matthew 28, Christ commissions His disciples to teach and preach, asserting His authority over the mission. As Ezra read the law, he acted as a type of Christ, bringing the Word of God to the people with authority, which is echoed in the New Testament where Jesus' teachings astonished the crowds (Matthew 7:29). The authority of the preacher is not from themselves but from the Word of God being faithfully expounded, reflecting the voice and will of Christ Himself.
