Here’s the point Van Til was driving at in the previous post (though the whole argument is worth reading, even if it is a bit long).
It would appear then that the theory of being that we have presented fits in with the notion of the Bible as an authoritative revelation of God. Such a being as the Bible speaks of could not speak otherwise than with absolute authority. In the last analysis we shall have to choose between two theories of knowledge. According to one theory God is the final court of appeal; according to the other theory man is the final court of appeal.
