Jonathan Edwards points out the judgments of God against the non elect promote redemption of the elect godly seed..
And therefore, God's destroying those enemies of the church by the flood belongs to this affair of redemption; for it was one thing that was done in fulfilment of the covenant of grace, as it was revealed to Adam: "I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head." 616616 Gen. iii. 15. This was only a destruction of the seed of the serpent in the midst of their most violent rage against the seed of the woman, when in the utmost peril by them. We read in Scripture of scarce any destruction of nations but that one main reason given for it is, their enmity and injuries against God s church; and doubtless this was one main reason of the destruction of all nations by the flood. The giants that were in those days, in all likelihood, got themselves renown by their great exploits against heaven, and against Christ and his church, the remaining sons of God that had not corrupted themselves. We read, that just before the world shall be destroyed by fire, "the nations that are in the four quarters of the earth, shall gather together against the church as the sand of the sea, and shall go up on the breadth of the earth, and compass the camp of the saints about, and the beloved city; and then fire shall come down from God out of heaven, and devour them," Rev. xx. 8, 9. And it seems there was that which was very parallel to it, just before the world was destroyed by water. And therefore their destruction was a work of God that did as much belong to the work of redemption, as the destruction of the Egyptians belonged to the redemption of the children of Israel out of Egypt, or as the destruction of Sennacherib's mighty army, that had compassed about Jerusalem to destroy it, belonged to God's redemption of that city from them. By means of this flood, all the enemies of God's church, against whom that little handful had no strength, were swept off at once. God took their part, appeared for them against their enemies, and drowned those of whom they had been afraid, in the flood of water, as he drowned the enemies of Israel that pursued them in the Red sea. Indeed God could have taken other methods to deliver his church: he could have converted all the world instead of drowning it; and so he could have taken another method than drowning the Egyptians in the Red sea. But that is no argument, that the method he did take, was not a method to show his redeeming mercy to them. By the deluge the enemies of
