What can you ever really know of other people's souls — of their temptations, their opportunities, their struggles? One soul in the whole of creation you do know: and it is the only one whose fate is placed in your hands. If there is a God, you are, in a sense, alone with Him.
C. S. LewisWe do know that no person can be saved except through Christ. We do not know that only those who know Him can be saved by Him.
C. S. LewisThere are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight.
