I downloaded the free PDF last evening and am thoroughly enjoying it so far.
From John Frame’s endorsement:
“Poythress does not merely claim that the discipline of linguistics allows a place for God, or that a theistic worldview provides useful context, or that engagement in such studies is somehow useful to Christians. Rather, he comes right in your face with the claims of Christ: God is not merely a possibility, not merely a conclusion, but the starting point for any understanding at all.”
