Psalms 79:10-12

10. Why should the heathen say, Where is their God? Here the people of God, in urging his name as a plea at the throne of grace: do so in a different sense from that in which they had urged it before. He extends his compassion towards us for his own name’s sake; for, as he is merciful, and will have our mouths stopped, that he alone may be accounted righteous, he freely pardons our sins. But here, the faithful beseech him that he would not allow his sacred name to be exposed to the blasphemies and insults of the wicked. From this we are taught that we do not pray in a right manner, unless a concern about our own salvation, and zeal for the glory of God, are inseparably joined together in our exercise. From the second clause of the verse, the same question may be raised which we have just now answered. Although God declares that he will execute vengeance upon our enemies, we are not warranted to thirst for revenge when we are injured. Let us remember that this form of prayer was not dictated for all men indiscriminately, that they might make use of it whenever impelled by their own passions, but that, under the guidance and instruction of the Holy Spirit, they might plead the cause of the whole Church, in common, against the wicked. If we would, therefore, offer up to God a prayer like this in a right manner, in the first place, our minds must be illuminated by the wisdom of the Holy Spirit; and, secondly, our zeal, which is often corrupted by the turbid affections of the flesh, must be pure and well-regulated; and then, with such a pure and well-tempered zeal, we may lawfully beseech God to show us, by evident examples, how precious, in his sight, is the life of his servants whose blood he avenges. The faithful are not to be understood as expressing any desire to be glutted with the sight of the shedding of human blood, as if they longed greedily after it: they only desire that God would grant them some confirmation of their faith, in the exercise of his fatherly love which is manifested when he avenges the wrongs done to his own people. It is farther to be noticed, that the appellation, the servants of God, is given to those who, nevertheless, were justly punished on account of their sins; for although he may chastise us, yet he does not forthwith cast us off, but, on the contrary, testifies thereby that our salvation is the object of his care. Again, we know that when the anger of God is extended over the whole body of the Church, as the good and the bad are mingled together in her, the former are punished in common with the latter, even as Ezekiel, Jeremiah, Daniel, and others, were carried into captivity. They were not, it is true, altogether faultless; but it is certain that so great a calamity was not brought upon the Jews on their account. In their person, there was rather set forth a spectacle to the ungodly, that they might be the more deeply affected.
