"Repentance is the doorway to the spiritual life, the only way to begin. It is also the path itself, the only way to continue. Anything else is foolishness and self-delusion. Only repentance is both brute-honest enough, and joyous enough, to bring us all the way home."
--Frederica Mathewes-Green, The Illumined Heart: The Ancient Christian Path of Transformation
(Editor's note: Sounds very much like the first of the 95 Theses of Martin Luther:
"Our Lord and Master Jesus Christ, when He said Poenitentiam agite, willed that the whole life of believers should be repentance." )
