Psalms 85:7

"O God, You shall turn us again, and make us alive" [Psalm 85:6]. Not as if we ourselves of our own accord, without Your mercy, turn unto You, and then You shall make us alive: but so that not only our being made alive is from You, but our very conversion, that we may be made alive. "And Your people shall rejoice in You." To their own evil they shall rejoice in themselves: to their own good they shall rejoice in You. For when they wished to have joy of themselves, they found in themselves woe: but now because God is all our joy, he that will rejoice securely, let him rejoice in Him who cannot perish. For why, my brethren, will you rejoice in silver? Either your silver perishes, or thou: and no one knows which first: yet this is certain, that both shall perish; which first, is uncertain. For neither can man remain here always, nor can silver remain here always: so too gold, so garments, so houses, so money, so broad lands, so, lastly, this light itself. Be not thou willing then to rejoice in these: but rejoice in that light which has no setting: rejoice in that dawn which no yesterday precedes, which no tomorrow follows. What light is that? "I," says He, "am the Light of the world." [John 8:12] He who says unto you, "I am the Light of the world," calls you to Himself. When He calls you, He converts you: when He converts you, He heals you: when He has healed you, you shall see your Converter, unto whom it is said, "Show us Your mercy, O Lord, and grant us Your salvation" [Psalm 85:7]: Your salvation, that is, Your Christ. Happy is he unto whom God shows His mercy. He it is who cannot indulge in pride, unto whom God shows His mercy. For by showing him His salvation He persuades him that whatever good man has, he has not but from Him who is all our good. […]

Show us, O Lord, Your mercy, and grant us Your salvation. That the Savior came down is a matter of God's mercy: the physician would not have come, had not very many been sick. Because very many were sick, therefore the physician came: because we were in need of mercy, therefore the Savior came.

They pray that God would, graciously to them and gloriously to himself, appear on their behalf: " Grant us thy salvation; grant it by thy promise, and then, no doubt, thou wilt work it by thy providence." Note, The vessels of God's mercy are the heirs of his salvation; he shows mercy to those to whom he grants salvation; for salvation is of mere mercy.

7 show us thy mercy, O L ORD , and grant us thy salvation. The church, in affliction and distress, is here, by direction from God, making her application to God. So ready is God to hear and answer the prayers of his people that by his Spirit in the word, and in the heart, he indites their petitions and puts words into their mouths.

Show us thy mercy, O Lord,....
