The grim reality of Genesis 6 is that the rebellion precipitating creation-wide judgment involves all humanity. Judgment looms for everyone—except for one man. Amid the spiraling wickedness of humanity and God’s solemn intention to bring judgment on that wickedness, Genesis 6:8 declares, “But Noah found grace [חֵן; khen] in the eyes of the LORD.” In a humanity of pervasive wickedness, Noah found grace. This seemingly obvious context is critical to a right understanding of the Noahic covenant. In Genesis 3:15, God had promised that He would sovereignly intervene and turn the enmity in the hearts of some men and women. Rather than being at enmity with Him, God would make certain people to be at enmity with the serpent. God has fulfilled that promise with Noah.
