'Only the Christian worldview locates the problem with the world not in any part of the world or in any particular group of people but in sin itself (our loss of relationship with God). And it locates the solution in God's grace (our restoration of a relationship with God through the work of Christ). Sin infects us all, and so we cannot simply divide the world into the heroes and villains. (And if we did, we would certainly have to count ourselves among the latter as well as the former). Without an understanding of the gospel, we will either be naively utopian or cynically disillusioned. We will be demonizing something that isn't bad enough to explain the mess we're in; and we will be idolizing something that isn't powerful enough to get us out of it. This is, in the end, what all the other worldviews do.
The Christian story line works beautifully to make sense of things and even to help us appreciate the truth embedded in stories that clearly come from another worldview.'
Timothy Keller, Every Good Endeavour, p.162.
