Please Study 2 Corinthians 3

"Foundational to this intellectualism, this rationalism, or however anyone wishes to name this emphasis on truth, is the doctrine that man is the image of God. One should not try to dilute this doctrine by picturing man as a container somewhere within which the image of God may be found. 1 Corinthians 11:7 does not say that man has the image of God; it says that man is the image of God. This image, which distinguishes man from animals, is rationality. It was not destroyed by the fall, for we are still human beings and not animals. We are till generically rational, though sin has considerably damaged our use of reason. We add up our check stubs incorrectly, and our emotions drive us into foolish conduct (or worse). But we are still human because we are the created image of God. Though we often believe falsehoods, we are still obligated to believe the truth. And if God causes us to believe, since faith is the gift of God, then we are slowly renewed in the knowledge and righteousness of our original creation." - Gordon H. Clark, What is Saving Faith?
