17. And the flood was forty days, etc. Moses copiously insists upon this fact, in order to show that the whole world was immersed in the waters. Moreover, it is to be regarded as the special design of this narrations that we should not ascribe to fortune, the flood by which the world perished; how ever customary it may be for men to cast some veil over the works of God, which may obscure either his goodness or his judgments manifested in them. But seeing it is plainly declared, that whatever was flourishing on the earth was destroyed, we hence infer, that it was an indisputable and signal judgment of God; especially since Noah alone remained secure, because he had embraced, by faith, the word in which salvation was contained. He then recalls to memory what we before have said; namely how desperate had been the impiety, and how enormous the crimes of men, by which God was induced to destroy the whole world; whereas, on account of his great clemency, he would have spared his own workmanship, had he seen that any milder remedy could have been effectually applied. These two things, directly opposed to each other, he connects together; that the whole human race was destroyed, but that Noah and his family safely escaped. Hence we learn how profitable it was for Noah, disregarding the world, to obey God alone: which Moses states not so much for the sake of praising the man, as for that of inviting us to imitate his example. Moreover, lest the multitude of sinners should draw us away from God; we must patiently bear that the ungodly should hold us up to ridicule, and should triumph over us, until the Lord shall show by the final issue, that our obedience has been approved by him. In this sense, Peter teaches that Noah’s deliverance from the universal deluge was a figure of baptism, (1 Peter 3:21;) as if he had said, the method of the salvation, which we receive through baptism, degrees with this deliverance of Noah. Since at this time also the world is full of unbelievers as it was then; therefore it is necessary for us to separate ourselves from the greater multitude, that the Lord may snatch us from destruction. In the same manner, the Church is fitly, and justly, compared to the ark. But we must keep in mind the similitude by which they mutually correspond with each other; for that is derived from the word of God alone; because as Noah believing the promise of God, gathered himself his wife and his children together, in order that under a certain appearance of death, he might emerge out of death; so it is fitting that we should renounce the world and die, in order that the Lord may quicken us by his word. For nowhere else is there any security of salvation. The Papists, however, act ridiculously who fabricate for us an ark without the word.
