In Matthew 3:1, Matthew uses the Greek word “preaching” to describe John the Baptist’s ministry. This word literally means “to proclaim as a herald.” By choosing to use this word to describe the preaching of John, Matthew is emphasizing John’s role as a herald for the King. As a herald, one’s authority comes from the content of the message and not from the messenger himself. He was not composing his own messages, but simply declaring the message of the King. This continues to be the role of Christian preachers. Namely, to declare the Word of God and not one’s own opinion. The best preaching, in fact the only preaching, is that which faithfully explains what God has already spoken.
In John’s example we can also see the primacy of preaching. Throughout the history of the church, preaching has been the primary way of communicating God’s truth to God’s people. In Matthew, John came preaching, Jesus came preaching, the disciples were sent preaching. In the book of Acts, Peter and Paul both preach. In church history, Augustine was a preacher, Chrysostom was a preacher, John Calvin and Martin Luther were above all else preachers, Charles Spurgeon was a preacher, D.L. Moody was a preacher, W.A. Criswell and Adrian Rogers were preachers, John MacArthur and John Piper are preachers! Whatever else the world may need, no need is greater than for God-called preachers to declare the same message as John the Baptist:“The King has come!”
