“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.”

“"Who redeemeth thy life from corruption" (ver. 4). Behold, "the body which is corrupted, weigheth down the soul." The soul then hath life in a corruptible body. What sort of life? It suffereth burdens, it beareth weights. How great obstacles are there to thinking of God Himself, as it is right that men should think of God, as if interrupting us from the necessity of human corruption? how many influences recall us, how many interrupt, how many withdraw the mind when fixed on high? what a crowd of illusions, what tribes of suggestions? All this in the human heart, as it were, teemeth with the worms of human corruption. We have set forth the greatness of the disease, let us also praise the Physician. Shall not He then heal thee, who made thee such as to be in health, hadst thou chosen to keep the law of health which thou hadst received? ...First think of thine own health. Sometimes a man is stricken in his own house, on his bed, with a more than usually manifest disorder; although this disorder too, which men dislike to contemplate, be plain; yet each man may be attacked with that sickness for which human physicians are sought, and may gasp with fever in his bed; perhaps he may wish to consider of his domestic affairs, to make some order or disposition relating to his estate or his house; at once he is recalled from such cares by the anxiety of his friends, plainly expressed around him, and he is advised to dismiss these subjects, and first to take thought for his health. This then is addressed unto thee, and to all men: if thou art not sick, think of other things: if thy very infirmity prove thee sick, first take heed of thy health. Christ is thy health: think therefore of Christ. Receive the cup of His saving Health, "who healeth all thine infirmities;" if thou shall choose, thou shall gain this Health. ...For thy life hath been redeemed from corruption: rest secure now: the contract of good faith hath been entered upon; no man deceives, no man circumvents, no man oppresses, thy Redeemer. He hath here made a barter, He hath already paid the price, He hath poured forth His blood. The only Son of God, I say, hath shed His blood for us: O soul, raise thyself, thou art of so great price. ..."He redeemeth thy life from corruption."”

“Finally, after redemption from all corruption, what remains except the crown of righteousness? Certainly, it remains, but even in it or under it, let there not be a swollen head, so that it may receive the crown. Listen, attend to the Psalm, how that crown does not want a swollen head. When it said: Who redeems your life from corruption; who crowns you, it says. And here you would have said: It crowns you, my merits confess, my virtue has done this: it is rendered as due, not given as a gift. Rather, listen to the Psalm. For you also say this: Every man is a liar. Listen to what God says: Who crowns you with compassion and mercy. He crowns you from His mercy, He crowns you from His compassion. For you were not worthy to be called, and when called to be justified, and when justified to be glorified. The remnants have been saved by the election of grace. But if by grace, it is no longer out of works: otherwise grace is no longer grace. For to him who works, the reward is not reckoned according to grace, but according to debt. The Apostle speaks: Not according to grace, but according to debt. However, He crowns you in compassion and mercy: and if your merits have preceded, God says to you: Examine your merits well, and you will see that they are my gifts.”

“Who redeemeth thy life from destruction,.... Not from temporal destruction, to which the natural life is subject, through diseases, dangerous occurrences, and the malice of enemies; to be delivered from which is a blessing, and for which God is to be praised; but from eternal destruction, the destruction of the body and soul in hell; and so the Targum, "who redeemest thy life from hell;'' to which destruction all men are liable through sin; their ways lead unto it, and grace only prevents it: the people of God are redeemed from sin, the cause of it; and from the curse of the law, in the execution of which it lies; and from Satan, the executor of it; and all this by Christ, who is the Redeemer appointed and sent, and who being mighty, and so equal to the work, has obtained eternal redemption; through which the saints are secure from going down to the pit of destruction, or from wrath to come; and this is a blessing they can never be enough thankful for; see Luk 1:68, who crowneth thee with lovingkindness and tender mercies; with all other blessings which flow from the lovingkindness and tender mercy of God, even all the blessings of the everlasting covenant, the sure mercies of David; all the spiritual blessings with which the saints are blessed in Christ, the grace given them in him, and the mercy kept with him for evermore; all things pertaining to life and godliness given in regeneration; the fruits of great love and abundant mercy, with all the other supplies of grace between that and eternal glory: "crowning" with these denotes an application and enjoyment of them, the great plenty and abundance of them, a being surrounded and loaded with them; as also the honour that goes along with them, which makes those that have them great and glorious, rich and honourable; as well as preservation and protection by them; these encompassing about as a crown the head, and as a shield the body; see Psa 5:12, where the same word is used as here.”
