Ps 102:3

“Hear ye all His rewards. "Who forgiveth all thy sin: who healeth all thine infirmities" (ver. 3). Behold His rewards. What, save punishment, was due unto the sinner? What was due to the blasphemer, but the hell of burning fire? He gave not these rewards: that thou mayest not shudder with dread: and without love fear Him. ...But thou art a sinner. Turn again, and receive these His rewards: He "forgiveth all thy sin." ...Yet even after remission of sins the soul herself is shaken by certain passions; still is she amid the dangers of temptation, still is she pleased with certain suggestions; with some she is not pleased, and sometimes she consenteth unto some of those with which she is pleased: she is taken. This is infirmity: but He "healeth all thine infirmities." All thine infirmities shall be healed: fear not. They are great, thou wilt say: but the Physician is greater. No infirmity cometh before the Almighty Physician as incurable: only suffer thou thyself to be healed: repel not His hands; He knoweth how to deal with thee. Be not only pleased when He cherisheth thee, but also bear with Him when He useth the knife: bear the pain of the remedy, reflecting on thy future health. ...Thou dost not endure in uncertainty: He who promised thee health, cannot be deceived. The physician is often deceived: and promiseth health in the human body. Why is he deceived? Because he is not healing his own creature. God made thy body, God made thy soul. He knoweth how to restore what He hath made, He knoweth how to fashion again what He hath already fashioned: do thou only be patient beneath the Physician's hands: for He hateth one who rejects His hands. This doth not happen with the hands of a human physician. ...”

“If you did not wish to be contentious, I think you would now see how correctly we understand what you are trying to explain differently. When the prophet said, "who forgives all your faults"—something that is done by the remission of all sins—he immediately added "who heals all your diseases." He wants us to understand the evils with which the saints will never finish their internal warfare until those evils are healed or, as far as possible in this life, progressively diminished. Not even when the virtue of chastity stands unshaken is there no sickness by which the flesh lusts against the spirit. When there is no sickness, the spirit does not lust against it, because it lusts in order at least by not consenting to obtain health, since it is unable to do so by not fighting. We are speaking of that whose resistance to us we perceive within us; if an alien nature, we must get rid of it; if our own, it must be healed. If we say it is an alien nature and must be gotten rid of, we agree with the Manichaeans. Let us, then, confess it is our own nature that must be healed, and thus we shall at the same time be clear of Manichaeans and Pelagians.”

“He is the Beginning, O God, in which you made heaven and earth. In this wonderful way you spoke and created them in your Word, in your Son, who is your strength, your wisdom and your truth.Who can understand this mystery or explain it to others? What is that light whose gentle beams now and again strike through to my heart, causing me to shudder in awe yet firing me with their warmth? I shudder to feel how different I am for it: yet in so far as I am like it, I am aglow with its fire. It is the light of Wisdom, Wisdom itself, which at times shines on me, parting my clouds. But when I weakly fall away from its light, those clouds envelop me again in the dense mantle of darkness that I bear for my punishment. For "my strength ebbs away for very misery," so that I cannot sustain my blessings. And so I shall remain until you, O Lord, who "have pardoned all my sins," also "heal all my mortal ills." For you will "rescue my life from deadly peril, crown me with the blessings of your mercy, content all my desire for good, restore my youth as the eagle's plumage is restored." "Our salvation is founded on the hope of something," and in endurance we await the fulfillment of your promises. Let those who are able listen to your fulfillment of your promises. Let those who are able listen to your voice speaking to their hearts. Trusting in your inspired words, I shall cry out, "What diversity, Lord, in your creatures! What wisdom has designed them all!" The Beginning is Wisdom, and Wisdom is the Beginning in which you made heaven and earth.”
