The cross and preaching

God did not ordain the cross of Christ or create the lake of fire 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 you 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 (Rev. 13:8; 2 Tim. 1:9) and for hell to be terrible (Matt. 25:41) so that we would have the clearest vision 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 the fire of hell. [John Piper, in Preaching the Cross.]
