I just started in on Michael Horton's new book, The Gospel-Driven Life: Being Good News People in a Bad News World. The Introduction was good enough to pull a few quotes from. Here's one where Horton explains the gospel in terms of our story, and The Story.
The Good News is not just a series of facts to which we yield our assent but a dramatic narrative that replots our identity. Think of it in terms of a theatrical play. Each week we come to church with our own scripts. If yours is anything like mine, it's "the show about nothing." Yet God descends to give us a new script: a rich plot in which our original character dies and is raised with the lead character. Instead of trying to find a supporting role for God in our play, God writes us into his script as a part of a growing cast for his new world. The script does not offer a blueprint for a new creation, if we will only follow certain steps for realizing it. Instead, through this gospel the Spirit sweeps us into the drama, into the new creation that has already been inaugurated.
