When my sin finds me out; when the cock crows; when I hear the voice "Thou art the man;" the shock of the sudden discovery to me of my guilt, under the eye of Jesus, "turning and looking on me;" moves me to tears and prayer. It is prayer; perhaps for the first time truly prayer. It is the abrupt cry, - "Lord save me; I perish." Blessed be God even that is enough.
