This is a common but narrow way of thinking about culture.
Culture is much broader.
Culture is the things people make, which reflect humanity's material needs, along with the ideas and the moral dispositions people carry within themselves. Put metaphorically, culture is to people what water is to fish. We must face the formidable task of understanding the elements of contemporary culture that distort and obscure the gospel. We must take the positive opportunities that God has created and structured into culture for honoring Him and making His mercy known in a dark world. We can learn how to use culture as an arena for creativity, thinking, and action in which we raise up the gospel and the biblical worldview for people to see an alternative vision of human life.
