The following quote comes from David Wells' book, The Courage to Be Protestant:

Let us not mince words.  If we could see more clearly God in the full blaze of His burning purity, we would not be on easy terms with all the sins that now infect our souls and breed easy compromises with the spirit of the postmodern age.  This is what leads to the casual ways in which we live our lives with their blatantly wrong priorities.  If we could see this more clearly, the church would be filled with much more repentance and, in consequence, much more joy, and much more authenticity.
