Is Human "Reason" Tainted by Sin?

The greatest minds in the Bible not not write books on apologeticd.  The greatest minds in the Bible were completely sold out to God. The men and women of the Bible who knew God knew that knowing Him for real involved going beyond mere discursive thinking. They knew that real knowledge of Yahweh involved superknowledge or epignosis!  They never focused on apologetics or the synergy of Faith and Reason.  A real conjoint relationship with Jesus Christ suspends such useless pretensions.
