When his light is taken away, nothing remains but blindness and darkness: when his Spirit is taken away, our hearts become hard as stones: when his guidance is withdrawn, we immediately turn from the right path: and hence he is properly said to incline, harden, and blind those whom he deprives of the faculty of seeing, obeying, and rightly executing.Institutes, Book 2, Chapter 4
