 Our original knowledge of God and his glory is muffled and impaired; it has been replaced (by virtue of sin) by stupidity, dullness, blindness, inability to perceive God or to perceive him in his handiwork. Our knowledge of his character and his love toward us can be smothered: it can even be transformed into a resentful thought that God is to be feared and mistrusted; we may see him as indifferent or even malignant.… The most important cognitive consequence of sin, therefore, is failure to know God. And this failure can have further cognitive consequences…. If we don’t know there is such a person as God, we don’t know the first thing (the most important thing) about ourselves, each other, and the world. (Plantinga 2000: 215 and 217)
