“…there is nothing impious in using arguments with unbelievers that employ their God-given reasoning abilities. Good reasoning is not ‘autonomous’ or ‘apostate,’ but rather a God-given way to discover truth.” p. 63 (Groothuis’ Christian Apologetics)
“Simply put, if a worldview fails to explain what it promises to explain, fails to make sense on its own terms (internal consistency), fails to describe what is there (objective and inner reality), fails to give intelligible meaning to life, or fails to be intellectually and culturally productive, it is disqualified from consideration. I will argue that Christianity passes these tests better than any of its competitors.” p. 72
