If the world is preserved, it is preserved for Jesus. When God hangs His war bow in the clouds, He is effectively saying, “I will hold back my wrath from this sin-cursed world.” Why? So that He can one day take that wrath upon Himself on the cross. The temporal peace of the Noahic covenant is the shadow; the eternal peace of the New Covenant is the substance.

Loved ones, in our exposition of Genesis 9, we took a specific theological stance regarding the Noahic Covenant. We argued that God made this covenant fundamentally with Noah (as a believing federal head) and that it functions as an administration of the Covenant of Grace. In this view, the preservation of the physical world is not an end in itself, but a means to ensure that the “Seed of the woman” (Gen. 3:15) could arrive to crush the serpent.

However, if you read widely within the Reformed tradition, you will find that this is not the only view. Excellent theologians have disagreed on the precise relationship between the rainbow and the cross. Is the Noahic Covenant purely a “common grace” contract with creation, distinct from salvation? Or is it an essential chapter in the story of redemption?

This excursus explores the theological debate regarding the Noahic Covenant, arguing that it is best understood as a subservient administration of the Covenant of Grace, while acknowledging the validity of the “Common Grace” view prevalent in Reformed theology.

The Case for Unity: An Administration of Grace

The position we have taken in this series—that the Noahic Covenant is part and parcel of the Covenant of Grace—rests on several key biblical pillars. This view has been held by stalwarts like Francis Turretin and Herman Witsius, and more recently by O. Palmer Robertson.

The Recipient of the Covenant

First, look at who stands at the center of the covenant: Noah. As we saw in Genesis 6:8, Noah “found favor” (grace) in the eyes of the Lord. He is a justified man, a “heir of the righteousness that comes by faith” (Heb. 11:7). God establishes this covenant with a believer, not with humanity in the abstract. Just as the Abrahamic covenant was made with Abraham and extended to his household, this covenant is made with Noah and extends to the whole world which is under his stewardship.

The Preservation of the Seed

Second, we must ask: Why does God promise not to destroy the world again? Is it simply because He loves trees and mountains? Scripture suggests a deeper motive. God has already promised that a Savior would come from the seed of Eve (Gen. 3:15). If God were to wipe out humanity every time they deserved it (which is constantly), the line of the Messiah would be extinguished. The physical preservation of the world is absolutely necessary for the spiritual redemption of the world. The stage must stand so the play can happen.
