To deny oneself means to give up one's bad habits; to root out of the heart all that ties us to the world; not to cherish bad thoughts and desires; to suppress every evil thought; to avoid occasions of sin; not to desire or to do anything out of self-love, but to do everything out of love for God. To deny oneself, according to St. Paul means "to be dead to sin. . . but alive to God."
-St. Innocent of Alaska, The Lenten Spring, SVS Press, p. 147, 19th Century
Nothing comes without effort. The help of God is always ready and always near, but is given only to those who seek and work, and only to those seekers who, after putting all their powers to the test, then cry out with their whole heart: "Lord, help us."
-St. Theophan the Recluse 19th Century
