As the human race multiplied following the Fall, the internal corruption of the heart manifested in external, worldwide rebellion. The narrative in Genesis: 6–11 covers two massive shifts in God’s dealings with humanity: the global Flood and the dispersion at the Tower of Babel.
By the time of Noah, the spiritual state of the world had reached a point of total depravity. The Scripture records:
“And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.” (Genesis 6:5, KJV)
In a righteous response to this universal rebellion, God determined to purge the earth through a cataclysmic Flood. Yet, Noah found grace in the eyes of the Lord. It is important to note that Noah was not saved because of his own works or merit, but because of his faith in God’s word.
This truth is most powerfully illustrated in Genesis 7:16: “and the Lord shut him in.” Noah did not close the door of the Ark to secure his own safety; the “hand” of God performed the final act of sealing. This signifies that God does the saving. Just as Noah had to enter the Ark by faith, it was God who provided the security and the salvation. Once the Lord shut that door, those inside were preserved by His power, while those outside were left to judgment. It serves as a timeless type of the believer’s security—salvation is a divine work, initiated and completed by God Himself.
Following the Flood, God established a covenant with Noah, symbolized by the rainbow, promising never again to destroy the earth by water. However, it was not long before humanity again sought independence from their Creator. At the Tower of Babel (Chapter 11), man attempted to build a kingdom centered on human pride.
By confounding their languages and scattering the nations, God halted this organized rebellion. This judgment serves as the bridge to the next major movement in Genesis. Having dealt with the nations as a whole, God would now set them aside for a time to call out one specific man—Abraham—through whom He would bless all the families of the earth and eventually bring the promised Redeemer.
