Gospel preaching is a serious endeavor. And the mantle of preaching isn't to be worn flippantly.

Because God is God, and the Bible is his word, the heralding and exposition of that word is central to the corporate life of his redeemed people. In his message at the inaugural Together for the Gospel Conference, John Piper explains why.

God did not ordain the cross of Christ or create the lake of fire³ in order to communicate the insignificance of belittling his glory. The death of the Son of God and the damnation of unrepentant human beings are the loudest shouts under heaven that God is infinitely holy, and sin is infinitely offensive, and wrath is infinitely just, and grace is infinitely precious, and our brief life — and the life of every person in your church and in your community — leads to everlasting joy or everlasting suffering. If our preaching does not carry the weight of these things to our people, what will? Veggie Tales? Radio? Television? Discussion groups? Emergent conversations?

God planned for his Son to be crucified (Revelation 13:8; 2 Timothy 1:9) and for hell to be terrible (Matthew 25:41) so that we would have the clearest witnesses possible to what is at stake when we preach. What gives preaching its seriousness is that the mantle of the preacher is soaked with the blood of Jesus and singed with fire of hell. That’s the mantle that turns mere talkers into preachers. Yet tragically some of the most prominent evangelical voices today diminish the horror of the cross and the horror of hell — the one stripped of its power to bear our punishment, and the other demythologized into self-dehumanization and the social miseries of this world.⁴

Oh that the rising generations would see that the world is not overrun with a sense of seriousness about God. There is no surplus in the church of a sense of God’s glory. There is no excess of earnestness in the church about heaven and hell and sin and salvation. And therefore the joy of many Christians is paper thin. By the millions people are amusing themselves to death with DVDs, and 107-inch TV screens, and games on their cell phones, and slapstick worship, while the spokesmen of a massive world religion write letters to the West in major publications saying, “The first thing we are calling you to is Islam . . . It is the religion of enjoining the good and forbidding the evil with the hand, tongue and heart. It is the religion of jihad in the way of Allah so that Allah’s Word and religion reign Supreme.”⁵ And then these spokesmen publicly bless suicide bombers who blow up children in front of Falafel shops and call it the way to paradise. This is the world in which we preach.

And yet incomprehensibly, in this Christ-diminishing, soul-destroying age, books and seminars and divinity schools and church growth specialists are bent on saying to young pastors, “Lighten up.” “Get funny.” “Do something amusing.” To this I ask, Where is the spirit of Jesus? “If anyone would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it, but whoever loses his life for my sake will find it” (Matthew 16:24–25). “If your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into hell” (Matthew 5:29). “Any one of you who does not renounce all that he has cannot be my disciple” (Luke 14:33). “If anyone comes to me and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be my disciple” (Luke 14:26). “Follow me, and leave the dead to bury their own dead” (Matthew 8:22). “Whoever would be first among you must be slave of all” (Mark 10:44). “Fear him who can destroy both soul and body in hell” (Matthew 10:28). “Some of you they will put to death . . . But not a hair of your head will perish. By your endurance you will gain your lives” (Luke 21:16-19).

Would the church-growth counsel to Jesus be, “Lighten up, Jesus. Do something amusing.” And to the young pastor: “Whatever you do, young pastor, don’t be like the Jesus of the Gospels. Lighten up.” From my perspective, which feels very close to eternity these days, that message to pastors sounds increasingly insane.
