An excellent review from Christianity Today of an intriguing book:
If we are justified by faith in Christ alone, then we need not be anxious to show how Spirit-filled we are by living extraordinary, radical lives. Having already received the promise of the Spirit in baptism—God’s promise, which we can trust he will keep—we are free to serve our neighbors with ordinary good works. We are freed from establishing our credentials before God or our own consciences. And we are even free, Horton states, to enjoy our neighbors as gifts rather than making them into our own projects, as if it was our job to transform their lives.
Horton argues that the underlying theology behind oft-heard calls to be wild and crazy radical believers—as if Christianity were an extreme sport—is works righteousness in a new, consumerist mode. For some time, radical has been a favorite word of advertisers and ideologues alike. Every website with something to sell now routinely promises a transformative experience.
Instead of another call to be radical, extraordinary, or transformative, Horton would have us return to the ordinary means of grace, those practices of the church in which God has promised to make himself known: preaching the gospel, teaching the faith, administering the sacraments, and worshiping with a local congregation. Instead of advertising life-changing experiences or the next big thing, the aim is a sustainable faith for the long haul. The great strength of being ordinary, after all, is that you can do it for a lifetime.
