I've heard plenty of Christians try to answer the why question by going back to the what. "You have to believe because Jesus is the Son of God." But that's answering the why with more what. Increasingly we live in a time in which you can't avoid the why question. Just giving the what (for example, a vivid gospel presentation) worked in the days when the cultural institutions created an environment in which Christianity just felt true or at least honorable. But in a post-Christendom society, in the marketplace of ideas, you have to explain why this is true, or people will just dismiss it.
Timothy KellerIt's impossible to have met the real Jesus and be indifferent. You either bow down in wonder OR go away offended.
Timothy KellerIf we pick out which parts of the Bible we dislike, we actually have a god we've created. How can that god ever call you out on anything?
Timothy KellerAt the end of history the whole earth has become the Garden of God again. Death and decay and suffering are gone. . . . Jesus will make the world our perfect home again. We will no longer be living 'east of Eden,' always wandering and never arriving. We will come, and the father will meet us and embrace us, and we will be brought into the feast.
Timothy KellerIt seems almost oxymoronic to believe that this new idealism has led to a new pessimism about marriage, but that is exactly what has happened. In generations past there was far less talk about "compatibility" and finding the ideal soul mate. Today we are looking for someone who accepts us as we are and fulfills our desires, and this creates an unrealistic set of expectations that frustrates both the searchers and the searched for.
