81. There is a beautiful cohesion between the words and their significance. A former proclamation threatens: I cannot endure longer contempt for my Word; my preachers and priests attain nothing with their infinite labor except derision. Nevertheless, as a father or good judge would gladly spare a son but is compelled by his wickedness to be severe, so, the Lord says, I do not destroy gladly the human race. I shall grant them one hundred and twenty years in which they may come to themselves, and during which I shall exercise mercy.
82. Horrible was the disaster, because neither the brothers nor the sisters of Noah were saved. It was necessary that the most earnest warning should precede, that, perhaps, they might be called back to repentance. To the Ninevites Jonah announces destruction within forty days, and they repent and are saved.
83. It is clear, therefore, that the heedlessness of the old world was very great, inasmuch as in the one hundred and twenty years of grace it obstinately persisted in its lusts, even deriding its pontiff Noah, the teacher of righteousness.
84. In our times, at the approach of the day of the Lord, almost the same condition obtains; we exhort to penitence the papists and our noblemen; the inhabitants of city and country we admonish not to continue despising the Word, since God will not leave this unavenged. But in vain we exert ourselves, as the Scripture says. A few faithful folk are edified and these are, one by one, gathered away from the face of sin, and "no man layeth it to heart," as is spoken in Isaiah 57, 1. But when God, in this way, has shaken out the wheat and gathered the grain in its place, what, think you, shall be the future of the chaff? Nothing else but to be burned with inextinguishable fire, Mt 13, 42. This shall be the lot of the world.
85. But the world does not understand how it can be that through the preaching of the Gospel the wheat should be separated from the chaff, to be gathered into the barn, while the chaff, that is, the throng of unbelievers sunk in idolatry and darkness, shall be consigned to the fire. It is written: "In a day of salvation have I helped thee; and I will preserve thee," Is 49, 8. Those who will neglect this day of salvation, will find God as an avenger, for he will not do useless labor in threshing empty chaff.
86. But the world is flesh; it does not obey. Yea, the nearer and more immediate the calamity, the more secure it is and the more readily it despises all faithful admonitions. Though this offense provokes the righteous, we should, notwithstanding, conclude that God does not reprove in vain the world through his Holy Spirit, nor that the Holy Spirit in the righteous is grieved in vain. Christ uses this as an example when he speaks of the wickedness and heedlessness of our age: "And as were the days of Noah, so shall be the coming of the Son of man," Mt 24, 37.
