Our job on earth

The idea that the gospel has something to say about the eternal destinies of people has been drummed into them for a long time. But they don't see that we are equally concerned about what Jesus taught us to pray: "May your kingdom come, and your will be done, on earth as it is in heaven."
Tim Keel, in An Efficient Gospel?
