'...the truths of experience are not self-explanatory. Instead they merely constitute the data that cries out to be explained within an overarching worldview. Why is it that the bits of matter we call our bodies have consciousness and are able to navigate the wolrd so effectively? Why are we capable of building societies with some measure of justice and compassion? As I write, NASA has just released stunning new photographs of the surface of Mars - but why is it possible for humans to calculate a trajectory and land a spacecraft on another planet? What kind of world permits these fascinating acheivements? Our claims as Christians is that only a biblically based worldview offers a complete and consistent explanantion of why we are capable of knowing scientific, moral and mathematical truths. Christianity is the key that fits in the lock of the universe.
Moreover, since all other worldviews are false keys, we can be absolutely confident, when talking with nonbelivers, that they themselves know things that are not accounted for by their own worldview - whatever it might be. Or, to turn it around, they will not be able to live consistently on the basis of their own worldview. Since their metaphysical beliefs do not fit the world God created, their lives will be more or less inconsistent with those beliefs. Living in the real world requires them to function in ways that are not supported by their worldview.
This creates a state of cognitive dissonance, and at that point of tension, the gospel may find an opening. In evangelism we can draw people's attention to the conflict between what they know on the basis of experience and what they profess in their stated beliefs - because that is a sure sign that something is wrong with their beliefs.'
