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 KellerThe essence of Christian obedience is not doโs and donโts but personal allegiance to Jesus.
Timothy KellerOne of the most frequent responses I get from non-Christian readers is: 'I'm not sure I agree with all this, but I must say this is the first book I've read by a Christian that didn't treat me like I was an idiot.'
Timothy KellerChristians don't believe that goodness gets you to heaven. Christians believe it's exhausting to rely on your own goodness to please God.
