It's important, though, that there are not "four gospels." There is only one gospel: the good news of what God has done through Christ to save the world. But we read that one gospel in four complementary accounts: The gospel, according to Matthew, according to Mark, according to Luke, according to John.

As Paul says, even though we as human beings know God, we refuse to acknowledge him. That's what Peter did. He refused even to "know" Jesus! Peter's failure reflects all our failure. It forces us to face the reality about ourselves. But the point of the story is that Jesus foretold this - he knew it was coming. And Jesus forgave Peter, when Peter confessed his love for Jesus. So the story illustrates both the horrible nature of sin, and the amazing reality of grace. That's essential to the whole meaning of the gospel.

The whole earth, then, belongs to Jesus. It belongs to him by right of creation, by right of redemption and by right of future inheritance - as Paul affirms in the magnificent cosmic declaration of Colossians 1:15-20. So wherever we go in his name, we are walking on his property. There is not an inch of the planet that does not belong to Christ. Mission then is an authorized activity carried out by tenants on the instructions of the owner of the property.

Mission means inviting all the peoples of the earth to hear the music of God's future and dance to it today.

Perhaps preachers today need to think about the assumptions that are common in their congregation - the plausibilities and comforting assurances - which may in themselves have biblical truth, but can easily become insurance policies waved around as immunity from any kind of serious evaluation of how we are living, whether we are truly following the Lord Jesus in the way he walked, whether we are doing righteousness and justice as God commanded.

I agree that we should regard all books of the Bible as equally inspired - and important. But some come into sharp focus at certain times, as particularly relevant and sharp in what they have to say to our culture at any given moment of history. And Jeremiah is a book for our times.

Only the gospel exposes the cancer of idolatry.
