What does the Bible say about the role of the preacher?

In the Bible, the preacher is primarily depicted as a voice—nothing more than a channel through which God's message is delivered to His people. As seen in Mark 1:2-3, God's messenger prepares the way for the Lord, emphasizing that the preacher does not create the message but merely conveys what God commissions him to preach. Additionally, the preacher is termed a servant (Romans 1:1), emphasizing his dedicated role in serving the gospel of God rather than promoting his own agenda. Furthermore, as an ambassador (2 Corinthians 5:20), the preacher represents Christ, delivering a message of reconciliation, encouraging sinners to come to Him.
