Every human culture is an extremely complex mixture of brilliant truth, married half-truths and over resistance to the truth. Every culture will have some idolatrous discourse within it. And yet every culture will have some witness to God’s truth in it. God gives out good gifts of wisdom, talent, beauty and skill completely without regard for merit. He casts them across a culture like seed, in order to enrich, brighten and preserve the world. Without this understanding of culture, Christians will tend to think that they can live self-sufficiently, isolated from and unblessed by the contributions of those in the world. Without an appreciation of God’s gracious display of his wisdom in the broader culture, Christians may struggle to understand why non-Christians often exceed Christians in moral practice, wisdom and skill. The doctrine of sin means that as believers we are never as good as our right worldview should make us. At the same time, the doctrine of our creation in the image of God, and an understanding of common grace, remind us that non-believers are never as flawed as their false worldview should make them.” -Tim Keller
