If man can know nothing truly, man can truly know nothing. We cannot know that the Bible is the Word of God, that Christ died for our sin, or that Christ is alive today at the right hand of the Father. Unless knowledge is possible, Christianity is non-sensical, for it claims to be knowledge. What is at stake in the twentieth century is not simply a single doctrine, such as the Virgin Birth, or the existence of Hell, as important as those doctrines may be, but the whole of Christianity itself. If knowledge is not possible to man, it is worse than silly to argue points of doctrine--it is insane.
