Os Guinness, in his excellent book, Renaissance, concerning the church in midst of the present challenges unprecedented in Western Culture, notes the culture changing and culture shaping power of the gospel, when the gospel is both declared by God’s People and is actively shaping God’s People.  When many of our churches are caving in pursuit of “relevance”, which is hoped will cause people to “like” the church, so we can keep our numbers up, I think Guinness offers a both prophetic and strategic word:

What we have here in the teaching of Jesus and the Scriptures, and amplified in Augustine, is the very heart of the secret of the culture-shaping power of the gospel in the church. When the church goes to either of two extremes, and is so “in the world” that it is of the world and worldly, or so “not of the world” that it is otherworldly and might as well be out of the world altogether, it is powerless and utterly irrelevant.  But when the church, through its faithfulness and its discernment of the times, lives truly “in” but “not of” the world, and is therefore the City of God engaging the City of Man, it touches off the secret of its culture-shaping power. For the intellectual and social tension of being “in” but “not of” the world provides the engagement-with-the-critical-distance that is the source of the church’s culture-shaping power.

In short, the decisive power is always God’s, through his Word and Spirit. But on her side the church contributes three distinct human factors to the equation: engagement, discernment, and refusal.

First, the church is called to engage and to stay engaged, to be faithful and obedient in that it puts aside all other preferences of its own and engages purposefully with the world as the Lord commands.

Second, the church is called to discern, to exercise its spiritual and cultural discernment of the best and worst of the world of its day, in order to see clearly where it is to be “in” and where it is to be “not of” that world.

Third, the church is called to refuse, a grand refusal to conform to or comply with anything and everything in the world that is against the way of Jesus and his kingdom.
