Or... The Last Sermon You'll Ever Hear
"Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning nor crying nor pain anymore, for the former things have passed away. ...Behold, I am making all things new....
It is done! I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give from the spring of the water of life without payment. The one who conquers will have this heritage, and I will be his God and he will be my son. But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death." Revelation 21:3-8 (ESV)
Mark Driscoll is wrong (well... partly). The last "sermon" that is preached in the bible, is not an angel proclaiming the gospel in Revelation 14:6. It is God himself, declaring the good news that the gospel is fulfilled. That the hope of everyone worshipper has come true: that God has arrived.
The gospel is God's message about himself. And from the declaration of determined intent in Genesis 3 to the declaration of accomplished redemption in Revelation 21, to preach it is to preach the words of God. The honour of being a preacher is entirely that God uses us to speak his gospel (because it comes from him), with his authority (because he commands it) to his people (because he loves us). And on that point, Mark is right. Preaching is not pagan; it is not passé; it is powerful, honourable and necessary.
Oh - and it's also foolish. (1 Corinthians 1:21)
