“The medium is the message” is how the phrase goes, and this is certainly true of preaching. If preaching is the medium, then its message is inherently tied to it…
The message is that Jesus is Lord, and God, and he is the Lord God who died for His people. He is the Lord and God who rose from the dead in victory over sin and Satan. And he is the Lord and God who now reigns in heaven, having ascended.
If Jesus is our Lord and our God, and if we have a duty to share that message, then the medium by which we share it must not be an ambiguous medium. We should never give the impression that the lordship of Christ is up for discussion or that it’s merely one person’s opinion. No, if Jesus is our Lord and our God, and if he is the one with all authority in heaven and on earth, that message must be declared. It must be listened to, and it must be heeded.
This is why preachers are so often called heralds. They are sent on commission by the King. This is the work of the Kingdom of King Jesus, not some democracy where everyone’s opinion counts.
