God’s covenant with Noah is often described as the covenant of common grace, and rightly so. In the wake of God’s judgment on the earth, the heart of humanity remains unchanged (cp. Gen. 6:5 and 8:21), yet for God to bring redemption to the world, some measure of preservation must be granted. Therefore, with strong covenantal language—berith occurs 7 times (vv. 9, 11, 12, 13, 15, 16, 17) in Genesis 9—God promises to uphold creation: “While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease” (8:22).
These promises to Noah envelope all creation and articulate God’s common grace—his universal beneficence towards a world filled with sin. In other words, common grace is common because it encompasses all humanity universally, not because it is mundane. Common grace is distinct from saving grace in that the former does not atone for sins or grant eternal life. Rather, it grants “grace” to the righteous and the unrighteous (cf. Matthew 5:45) and provides a historical context for saving grace to operate.
That being said, common grace is not equally apportioned. It is not like the periodic table, where every element possesses the same atomic weight. Rather, common grace is specific in that it often depends upon the saving grace given to God’s chosen people. In other words, just as common grace is promised through the Noahic covenant, so common grace continues to be mediated through other covenantal mediators. In Scripture, the first instance of this is Abraham.
