Isaac the Syrian: “he who confesses his pain is near to health.”

“Gratefulness on the part of the recipient spurs on the giver to bestow gifts larger than before. He who embezzles petty things is also false and fraudulent concerning things of importance.
   The sick one who is acquainted with his sickness is easily to be cured; and he who confesses his pain is near to health. Many are the pains of the hard heart; and when the sick one resists the physician, his torments will be augmented.
   There is no sin which cannot be pardoned except that one which lacks repentance, and there is no gift which is not augmented save that which remains without acknowledgement. For the portion of the fool is small in his eyes.”

– Isaac the Syrian, From homily 2
