“"Sweet is the Lord to all, and His compassions reach into all His works" (ver. 9). Hear the Scripture: "I will not the death of a sinner, but rather that he should turn, and live." By these words of God, he is brought back to hope; but there is another snare to be feared, lest through this very hope he sin the more. What then didst thou also say, thou who through hope sinnest yet more? "Whensoever I turn, God will forgive me all; I will do whatsoever I will." Say not then, "To-morrow I will turn, to-morrow I will please God; and all to-day's and yesterday's deeds shall be forgiven me." Thou sayest true: God hath promised pardon to thy conversion; He hath not promised a to-morrow to thy delay.”

“The Lord is good to all,.... Which is to be understood not of the general and providential goodness of God to all men, to all his creatures, and the works of his hands; but of the special goodness of Christ before mentioned, Psa 145:7; which extends to all the chosen people of God; who are all loved by Christ, redeemed by him, justified and glorified by him; and to Gentiles as well as Jews; for whom he tasted death, laid down his life a ransom for them, and became the propitiation for their sins. Hence his Gospel has been sent to both; and some of each have been effectually called by his grace, and more will. This shows this psalm belongs to Gospel times, in which the grace of Christ appears more large and extensive: and his tender mercies are over all his works; meaning not all the creatures his hands have made; though he has a tender regard to them, and is kind and merciful to them all; but such as are made new creatures in him and by him, who are eminently called his workmanship, the work of his hands; these, all of them, share in his special mercy and goodness; see Eph 2:10.”

“Works. The people of Israel (ver. 10., and Psalm lxxxix. 18.; Ferrand) and all mankind, who are all invited to embrace the true faith, and the mercy of God. (Calmet) — The effects of mercy shine forth above all his other works, in the redemption, and in the recalling of sinners, when they have gone astray. (Worthington) — This sense is good, but not literal. His mercy extends to all. (Berthier) — Yet he punishes the reprobate for ever, chastising their works. (St. Augustine)”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
