Nearly all great Christians describe a time when they feel that God has pulled away from them and His presence is not near as they have grown accustomed. John of the Cross describes in detail this experience and explains that this is simply a kind of spiritual surgery. God is not absent, in fact he is closer than ever doing necessary work on our souls in this apparent absence. This is bitter medicine for shallow Christians, but great comfort for those who have walked this path and wondered what God was doing. The time will come, John assures us, when we will see this "dark night" as one of the sweetest in our lives.
A difficult classic. Written in the 1500s. The title has since become a catch phrase meaning all sorts of things other than what the original author meant - Christians need to learn about the dark night of the soul.
