James M. Grier in Essays on the Christian Worldview:
... In his natural state the unregenerate man suppresses every aspect of God's natural and special revelation. The evidence in him, around him, and in Scripture is sufficient and final. There is no weakness in the evidence. The problem is that man cannot see. He doesn't need more evidence; he needs new birth. The living, abiding Word of God as self-attestingly sure, blessed by the regenerating activity of the Holy Spirit, is his only hope.
