Genesis 6 Summary – The Corruption of Humanity and the Preparation for the Flood

I. The Wickedness of Humanity and the Limitation of Lifespan (Genesis 6:1-4)

The chapter begins by describing the rapid increase of human population and the intermingling of the “sons of God” with the “daughters of men” (6:1-2). Various interpretations exist regarding the identity of the “sons of God,” ranging from angelic beings to the godly line of Seth. Regardless of the interpretation, the outcome is clear: the mixing of these groups contributes to the pervasive wickedness of humanity (6:4).

In response to the growing corruption, God decides to limit the human lifespan to 120 years (6:3). This declaration marks a significant shift from the long lifespans of the antediluvian patriarchs in Genesis 5.

II. God’s Grief and Decision to Judge the Earth (Genesis 6:5-8)

God observes the wickedness of humanity, with every inclination of the human heart being evil continually (6:5). This state of affairs grieves God to the point that He regrets creating humanity (6:6). As a result, God decides to bring judgment upon the earth in the form of a catastrophic flood, purging the earth of its wickedness (6:7). Amid the corruption, Noah, a righteous man, finds favor in the eyes of the Lord (6:8).

III. Noah’s Righteousness and God’s Instructions (Genesis 6:9-22)

Noah is described as a just and blameless man who walks with God, setting him apart from the wickedness that surrounds him (6:9). God informs Noah of His intention to destroy the earth and provides detailed instructions on the construction of the ark, a massive vessel designed to preserve human and animal life during the flood (6:13-16).

God establishes a covenant with Noah, promising to save him, his family, and representatives of every living creature on the ark (6:18). Noah demonstrates his faith and obedience by following God’s instructions precisely, constructing the ark and gathering the designated animals (6:22).


Genesis 6 paints a vivid picture of the depths of human depravity, the limitation of the human lifespan, and the necessity for divine judgment. The Great Flood serves as a stark reminder of the consequences of sin and the importance of obedience and faithfulness in our relationship with God. In the midst of humanity’s corruption, Noah stands out as a beacon of righteousness, illustrating the power of faith to preserve and protect in the face of judgment.

As we reflect on the events and lessons of Genesis 6, we are reminded of the seriousness with which God regards sin and the lengths He is willing to go to eradicate it. The limitation of the human lifespan to 120 years serves as a tangible expression of God’s response to sin. At the same time, the story of Noah and the ark highlights God’s grace and mercy, offering hope and salvation even in the midst of judgment.
