Preaching entails doing the work of a herald: to publicly proclaim or eagerly advocate a religious message or belief. This bold action is fundamental to Christianity. Because since in the wisdom of God, the world through its wisdom did not know Him, God was pleased through the foolishness of what was preached to save those who believe (1 Corinthians 1:21, BSB). Preaching is not merely the job of an exclusive group of professional theologians Jesus commissioned all of His followers to do it (Matthew 18:18-20). And like Peter and John who preached powerfully as ordinary men with no special training (Acts 4:13), we can too.
How do we do this? We make ourselves available for God to share His ideas with us. Then, we train ourselves to speak His ideas. We never just eat the Word to fill our own spirits, we always prepare a meal from what God provides for us to share with others. The result is that our spirits become a theatre of revelation and our lives, a letter read by men everywhere (see 2 Corinthians 3:2).
Preaching is simply speaking with the intention of convincing someone of God’s perspective and always has the emphasis on Jesus. We do not need a pulpit to do this. We have ample opportunities to preach every day: Whenever someone asks for advice; whenever we have a Bible study with our kids; whenever we discuss events with colleagues; whenever someone speaks bad news.
Great rewards await the faithful preacher (1 Cor 3:8, Matt. 25:23, Rev. 22:12).
