From "Keys to a deeper life" The article on "The deeper life what is it" Pgs 30-31

"It has been the unanimous testimony of the greatest Christian souls that the nearer they drew to God the more acute became their consciousness of sin and their personal unworthiness. The Purest souls never knew how pure they were and the greatest saints never guessed that they were great. The very thought that they were Good or great would have been rejected by them as a temptation of the devil.

They were so engrossed with gazing upon the face of God that they spent scarce a moment looking at themselves. They were suspended in the sweet paradox of spiritual awareness where they knew  that they were clean through the blood of the Lamb and yet felt that they deserved only death and hell as their just reward. This feeling is strong in the writings of Paul and is found also in most devotional books and among the greatest and most loved Hymns."
