'A Christianity that is without friction in the culture is a Christianity that dies. Such religion absorbs the ambient culture until it is indistinguishable from it, until, eventually a culture asks what the point is of the whole thing. A Christianity that is walled off from the culture around it is a Christianity that dies. The gospel we have received is a missionary gospel, one that must connect to those on the outside in order to have life. Our call is to an engaged alienation, a Christianity that preserves the distinctiveness of our gospel while not retreating from our callings as neighbors, and friends, and citizens.'
Russell Moore, Onward: Engaging the Culture without Losing the Gospel, p.8.
