No one can heal my disease except He Who knows the depths of the heart.
How many times have I set boundaries for myself and built walls between myself and sin! But my thoughts transgressed the boundaries and my will tore down the walls, for the boundaries were not secured by fear of God, and the walls were not founded on sincere repentance.
And again I knock at the door, that it may open for me. I do not cease to ask that I may receive what I request; and I know no shame in seeking Thy mercy, O Lord.
Wrench me from the mire of my iniquities, that I may not be forever sullied by them. Deliver me from the jaws of the enemy, who roars as a lion and desires to swallow me up.
Rouse Thy strength and come, that Thou mightest save me. Beam Thy lightning and disperse his power, that he may be struck with fear and flee from Thy face, for he has not the strength to stand before Thee and before the face of those who love Thee. As soon as he perceives a sign of Thy grace, he is taken with fear of Thee and withdraws from such with shame.
from the Spiritual Psalter of St. Ephraim the Syrian
