200. Today our life is very brief, still to what lengths human nature will go is sufficiently in evidence. What may we imagine the condition to have been in such a long existence, in which the bitterness and vehemence of human nature were even stronger? Today we are naturally much more dull and stupid, and yet men singularly gifted rush into wickedness. It is afterward said that all flesh had corrupted its way upon the earth, only Noah was just and upright. 201. From these two words we may gather the thought that Noah is held to be "just" as he honored the first table and "upright" as he honored the second. "Just" he is called, because of his faith in God, because he first believed the general promise with respect to the seed of woman and then also the particular one respecting the destruction of the world through the flood and the salvation of his own offspring. On the other hand he is called "upright" because he walked in the fear of God and conscientiously avoided murder and other sins with which the wicked polluted themselves in defiance of conscience. Nor did he permit himself to be moved by the frequent offenses of men most illustrious, wise and apparently holy. 202. Great was his courage. Today it appears to us impossible that one man should oppose himself to all mankind, condemning them as evil, while they vaunt the Church and God's Word and worship, and to maintain that he alone is a son of God and acceptable before him. Noah, accordingly, is a marvelous man, and Moses commends this same greatness of mind when he plainly adds "in his generation," or "in his age," as if he desired to say that his age was indeed the most wicked and corrupt. 203. Above, in the history of Enoch, we explained what it means to walk with God, namely, to advocate the cause of God in public. To be just and upright bespeaks private virtue, but to walk with God is something public--to advocate the cause of God before the world, to wield his Word, to teach his worship. Noah was not simply just and holy for himself but he was also a confessor; he taught others the promises and threats of God, and performed and suffered all that behooves a public personage in an age so exceedingly wicked and corrupt.
