Jeremiah 29:7

Because the life of the flesh is the soul, so the blessed life of humankind is God, of whom the sacred writings of the Hebrews say, "Blessed are people whose God is the Lord." Miserable, therefore, are people who are alienated from God. Yet even this people has a peace of its own that is not to be lightly esteemed, though, indeed, it shall not in the end enjoy it, because it makes no good use of it before the end. But it is our interest that it enjoys this peace meanwhile in this life. As long as the two cities are combined, we enjoy the peace of Babylon. For from Babylon the people of God is so freed that it meanwhile travels in its company. Therefore the apostle also admonished the church to pray for kings and those in authority, assigning as the reason "that we may live a quiet and tranquil life in all godliness and love." And the prophet Jeremiah, when predicting the captivity that was to befall the ancient people of God and giving them the divine command to go obediently to Babylonia and thus serve their God, counseled them also to pray for Babylonia, saying, "In its peace you will have peace"—the temporal peace that the good and the wicked together enjoy.
