Genesis 6 explains why God decided to send a flood over the earth, and why one man, Noah, was spared. The chapter describes a world where wickedness had grown so widespread that the LORD grieved over humanity, yet it also introduces a man who found favor in God’s eyes. Readers come to this chapter to understand the reasons behind the flood story and to see how divine judgment and mercy meet at the start of the Noah narrative.
Genesis 6 Summary
The chapter opens with an unusual account of human multiplication and a strange mingling between “God’s sons” and human women, which produces a people described as the Nephilim and “mighty men.” The LORD responds by limiting the span of human life to one hundred twenty years, and then observes that human wickedness has become constant and pervasive, which grieves him deeply.
The focus then narrows to God’s decision to destroy the earth’s creatures and humanity alike. Yet the story turns on a single sentence: Noah found favor in the LORD’s eyes. Noah is introduced as righteous and blameless, a man who walked with God, and the chapter closes with God giving him detailed instructions to build a great ship.
The flow moves from a widening corruption, to divine grief and resolve, to a rescue plan centered on one faithful household. Noah’s obedience at the end of the chapter answers the widespread violence described throughout.
Background and Setting
Genesis is the first book of the Christian Old Testament and the first book of the Jewish Torah. Traditionally it is attributed to Moses, though many scholars today see it as having been shaped from earlier sources over a long period, with its final form often dated to the period of Israel’s exile or the years after it. Its opening chapters address universal questions about God as Creator, the origin of sin, and the spread of human wickedness.
The book was written for a community that needed to understand its origins and identity under God. Chapter 6 sits between the genealogies and creation accounts of earlier chapters and the full flood narrative that follows, forming the bridge that explains why the flood happens and how God chooses to preserve life through Noah.
Genesis 6 Section by Section
Verses 1-4: The Days Before the Flood
1 When men began to multiply on the surface of the ground, and daughters were born to them, 2 God’s sons saw that men’s daughters were beautiful, and they took any that they wanted for themselves as wives.
Genesis 6:1-2 (WEB)
These opening verses describe a time when the human population grew and new relationships formed across lines the text presents as unusual. The phrase “God’s sons” has been read in several ways across Christian and Jewish tradition, including as divine beings, as the line of Seth, or as powerful human rulers. Because the passage is brief and debated, it is wise to hold interpretations with humility and focus on the point the text clearly makes: the world was moving away from God’s order.
The result, described in verse 4, is a people called the Nephilim and figures known as “mighty men of renown.” Whatever their exact identity, the narrative presents them as a sign of growing disorder. The section is less about explaining the details of these figures and more about showing how far the human story had drifted by the time God acted.
Verses 5-8: God’s Grief and Resolve
5 The LORD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of man’s heart was continually only evil. 6 The LORD was sorry that he had made man on the earth, and it grieved him in his heart.
Genesis 6:5-6 (WEB)
Here the chapter shifts from description to God’s inner response. The LORD sees that human wickedness is great and that the inclination of human hearts is continually evil. The Hebrew language here is strong and emotional, and the text speaks of God being grieved in his heart, which shows a relational God who cares deeply about the state of creation rather than a distant judge.
Verse 7 records God’s decision to destroy what he made, including humans and animals. Verse 8 then pivots sharply with a single line of grace: Noah found favor in the LORD’s eyes. This short sentence shapes the whole account, reminding readers that judgment in Genesis is always set within God’s larger purpose of preservation.
Verses 9-12: The Righteous Man in a Corrupt Age
This is the history of the generations of Noah: Noah was a righteous man, blameless among the people of his time. Noah walked with God.
Genesis 6:9 (WEB)
The text now introduces Noah more fully. He is described as righteous, blameless among the people of his time, and as one who walked with God. Walking with God is a phrase used elsewhere in Scripture for a life of faithful companionship, and it suggests that Noah’s goodness was rooted in relationship rather than in outward status or achievement.
Verses 11 and 12 repeat the theme of corruption, saying the earth was filled with violence and that all flesh had corrupted its way. The repetition is deliberate. Noah stands out not because his world was better, but because he remained faithful within a world that was not.
Verses 13-22: The Command to Build and Obey
13 God said to Noah, “I will bring an end to all flesh, for the earth is filled with violence through them. Behold, I will destroy them and the earth. 14 Make a ship of gopher wood. You shall make rooms in the ship, and shall seal it inside and outside with pitch.
Genesis 6:13-14 (WEB)
God speaks directly to Noah, announcing that he will bring an end to all flesh and giving precise instructions for building a ship of gopher wood. The specific dimensions, sealing with pitch, and multiple levels show that the rescue will be carefully engineered rather than left to chance. Readers often notice how practical these details are, which makes the story feel grounded in real human labor.
The section ends with God’s promise of a covenant and the command to bring living creatures into the ship. The chapter concludes with a simple, powerful statement that Noah did all that God commanded him. Obedience in the face of a judgment no one else seemed to anticipate becomes the human response that the chapter holds up as the faithful pattern.
Key Themes in Genesis 6

Lessons From Genesis 6 for Today
Many people today feel that the surrounding culture has drifted far from what they believe is good, whether in how families are formed, how neighbors treat one another, or how public life is conducted. Genesis 6 reminds readers that God sees these patterns clearly and does not treat them lightly. It also shows that God does not leave faithful people without a way forward, even when the wider world seems set on a destructive course.
For someone quietly keeping their integrity at work or raising children with values that run against popular trends, Noah offers encouragement. His story suggests that faithfulness does not require a majority, and that obeying God in ordinary, sometimes unpopular steps can be the means by which God preserves what matters most. Like Noah, a believer may be asked to build something patiently over many years before the purpose becomes visible.
Questions for Reflection
- What does it mean to you that God is described as grieved by human wickedness?
- In what ways do you see the pressures of your own culture pulling you away from faithful living?
- What might “walking with God” look like in your daily routines and decisions?
- How does Noah’s careful obedience challenge your own patterns of responding to God’s instructions?
- Where in your life do you need to trust God’s promise of preservation in the middle of uncertainty?
A Prayer From Genesis 6
Lord, you see the wickedness and violence in the world, and you do not look away from it. Thank you that you grieve over sin, and that your judgment is never careless or cruel. Help me to take seriously what grieves you and to examine my own heart honestly before you. Shape me, as you shaped Noah, into someone who walks with you faithfully even when those around me do not. Give me the patience to obey you in small, ordinary steps, trusting that you are at work in ways I cannot yet see. Amen.
