VII. Here are several pleas and arguments to enforce the petitions. God gives us leave not only to pray, but to plead with him, which is not to move him (he himself knows what he will do), but to move ourselves, to excite our fervency and encourage our faith. 1. They disdain a dependence upon any righteousness of their own; they pretend not to merit any thing at God's hand but wrath and the curse (v. 18): "We do not present our supplications before thee with hope to speed for our righteousness, as if we were worthy to receive thy favour for any good in us, or done by us, or could demand any thing as a debt; we cannot insist upon our own justification, no, though we were more righteous than we are; nay, though we knew nothing amiss of ourselves, yet are we not thereby justified, nor would we answer, but we would make supplication to our Judge." Moses had told Israel long before that, whatever God did for them, it was not for their righteousness, Deut. ix. 4, 5. And Ezekiel had of late told them that their return out of Babylon would be not for their sakes, Ezek. xxxvi. 22, 32. Note, Whenever we come to God for mercy we must lay aside all conceit of, and confidence in, our own righteousness. 2. They take their encouragement in prayer from God only, as knowing that his reasons of mercy are fetched from within himself, and therefore from him we must borrow all our pleas for mercy, and so give honour to him when we are suing for grace and mercy from him. (1.) "Do it for thy own sake (v. 19), for the accomplishment of thy own counsel, the performance of thy own promise, and the manifestation of thy own glory." Note, God will do his own work, not only in his own way and time, but for his own sake, and so we must take it. (2.) "Do it for the Lord's sake, that is, for the Lord Christ's sake," for the sake of the Messiah promised, who is the Lord (so the most and best of our Christian interpreters understand it), for the sake of Adonai, so David called the Messiah (Ps. cx. 1), and mercy is prayed for for the church for the sake of the Son of man (Ps. lxxx. 17), and for thy Word's sake, he is Lord of all. It is for his sake that God causes his face to shine upon sinners when they repent and turn to him, because of the satisfaction he has made. In all our prayers that therefore must be our plea; we must make mention of his righteousness, even of his only, Ps. lxxi. 16. Look upon the face of the anointed. He has himself directed us to ask in his name. (3.) "Do it according to all thy righteousness (v. 16), that is, plead for us against our persecutors and oppressors according to thy righteousness. Though we are ourselves unrighteous before God, yet with reference to them we have a righteous cause, which we leave it with the righteous God to appear in the defence of." Or, rather, by the righteousness of God here is meant his faithfulness to his promise. God had, according to his righteousness, executed the threatening, v. 11. "Now, Lord, wilt thou not do according to all thy righteousness? Wilt thou not be as true to thy promises as thou hast been to thy threatenings and accomplish them also?" (4.) "Do it for thy great mercies (v. 18), to make it to appear that thou art a merciful God." The good things we ask of God we call mercies, because we expect them purely from God's mercy. And, because misery is the proper object of mercy, the prophet here spreads the deplorable condition of the church before God, as it were to move his compassion: "Open thy eyes and behold our desolations, especially the desolations of the sanctuary. O look with pity upon a pitiable case!" Note, The desolations of the church must in prayer be laid before God and then left with him. (5.) "Do it for the sake of the relation we stand in to thee. The sanctuary that is desolate is thy sanctuary (v. 17), dedicated to thy honour, employed in thy service, and the place of thy residence. Jerusalem is thy city and thy holy mountain (v. 16); it is the city which is called by thy name," v. 18. It was the city which God had chosen out of all the tribes of Israel, to put his name there. "The people that have become a reproach are thy people, and thy name suffers in the reproach cast upon them (v. 16); they are called by thy name, v. 19. Lord, thou hast a property in them, and therefore art interested in their interests; wilt thou not provide for thy own, for those of thy own house? They are thine, save them," Ps. cxix. 94.
