"As soon as you turn away - however slightly - from God, and no longer place your trust in Him, things go awry; for then the Lord withdraws, as though saying: 'You have put your trust in something else - very well, rely on that instead.' And whatever it may be it proves utterly worthless."
- St. Theophan the Recluse as found in The Art of Prayer: An Orthodox Anthology, Timothy Ware, ed., Faber and Faber, 1966, p. 259.
