Genesis 6 explains why God decided to send a flood, and why one man named Noah found favor in his eyes. People usually read it to understand the strange account of “sons of God” and “daughters of men,” and to see how the chapter sets up the story of the ark. The short answer is that the world had become deeply corrupt, God grieved over it, and yet God chose to preserve a righteous family and a remnant of creation through a coming judgment.
Genesis 6 Summary
The chapter opens by describing how humanity multiplied across the earth. It then reports a troubling episode in which divine beings, called “God’s sons,” take human women as wives, and the text says this produced the Nephilim and mighty men of old. God responds by limiting human lifespan to 120 years, then observes that human wickedness has become constant and pervasive, and he regrets creating humanity.
From there the chapter moves toward judgment. God resolves to destroy the human race and the animal world along with it, but a single exception stands out: Noah, described as righteous and blameless, who walked with God. The final section turns to Noah’s family and God’s instructions for building a large vessel, with the promise of a covenant and provision for the animals to be preserved alive.
The chapter therefore moves from a broad picture of human decline to the narrowing focus on one household. Judgment and mercy are set side by side, and the reader is prepared for the flood account that follows.
Background and Setting
Genesis is the first book of the Hebrew Bible and the Christian Old Testament, and it forms the opening section of the Torah or Pentateuch. Tradition attributes the Pentateuch to Moses, though many modern scholars see it as drawn from several sources shaped over time, with the final form likely reaching its shape during or after the exile. Most readers place the events of Genesis in a primeval setting that precedes the patriarchs, and the book was written to a community of Israel seeking to understand its origins and its relationship to God.
Chapter 6 sits between the genealogies of Adam’s descendants in chapter 5 and the detailed flood narrative that begins in chapter 6 and continues through chapter 9. It acts as the hinge that moves the story from human increase to divine judgment, and it introduces Noah as the figure through whom God will continue his purpose.
Genesis 6 Section by Section
Verses 1-4: The Days of the Nephilim
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 humanity spreading across the earth and a troubling intermingling between “God’s sons” and human daughters. Interpreters have long debated the identity of the “sons of God,” with some reading them as divine beings, others as the line of Seth, and others as powerful human rulers. Whatever the exact meaning, the passage shows human society moving away from the order God intended, with appetite and self-direction replacing trust and obedience.
Verse 4 introduces the Nephilim and “mighty men of old,” figures whose reputation the text notes but does not fully explain. The point is less about giants and more about a world where strength and renown have become detached from righteousness, setting up the moral crisis that follows.
3 The LORD said, “My Spirit will not strive with man forever, because he also is flesh; so his days will be one hundred twenty years.” 4 The Nephilim were in the earth in those days, and also after that, when God’s sons came in to men’s daughters and had children with them. Those were the mighty men who were of old, men of renown.

Verses 5-8: God’s Grief Over Human Wickedness
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 narrative shifts from description to divine assessment. God sees that human wickedness is great and that the inclination of human thoughts has become continually evil. The language is strikingly emotional: God is said to be sorry and grieved in his heart. This is not a portrait of a deity caught off guard, but of a holy God whose relationship with his creation is personal and whose response to sin carries real weight.
Verse 7 announces the decision to destroy humanity along with the animals, and verse 8 turns with the words “But Noah found favor.” The contrast is the emotional center of the section. Judgment is coming, yet grace is already present in the life of one man.
7 The LORD said, “I will destroy man whom I have created from the surface of the ground—man, along with animals, creeping things, and birds of the sky—for I am sorry that I have made them.” 8 But Noah found favor in the LORD’s eyes.

Verses 9-12: Noah, the Righteous Man
9 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. 10 Noah became the father of three sons: Shem, Ham, and Japheth.
Genesis 6:9-10 (WEB)
Noah is introduced with a careful description: righteous, blameless among his contemporaries, and one who walked with God. The phrase “walked with God” recurs in Scripture as a picture of steady, faithful relationship rather than occasional religious activity. Noah’s three sons are named as well, which signals that his household will be central to what follows.
Verses 11 and 12 repeat the diagnosis of the earth as corrupt and filled with violence, emphasizing that the corruption is universal. Noah stands out not because he was flawless in every way, but because his life was oriented toward God in a world moving the other direction.
11 The earth was corrupt before God, and the earth was filled with violence. 12 God saw the earth, and saw that it was corrupt, for all flesh had corrupted their way on the earth.
Genesis 6:11-12 (WEB)
Verses 13-22: The Covenant and the Ark
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, explaining the judgment and giving detailed instructions for building an ark of gopher wood. The specifications of length, width, height, and internal levels show that this is a serious and carefully designed project, and the sealing with pitch points to protection against the waters to come.
The chapter closes with God’s promise to establish a covenant with Noah and to preserve his family and the animals. Verse 22 records Noah’s response in simple, obedient terms: he did all that God commanded. The passage ends where it began, with a focus on faithful response to God’s word.
21 Take with you some of all food that is eaten, and gather it to yourself; and it will be for food for you, and for them.” 22 Thus Noah did. He did all that God commanded him.

Lessons From Genesis 6 for Today
Genesis 6 invites readers to examine the direction of their own culture and their own hearts. When a community normalizes what God calls wrong, it can be tempting to assume that no one will notice or that nothing will change. The chapter reminds us that God takes sin seriously, and it also shows that he does not leave faithful people without a path forward.
For someone living in a workplace or neighborhood where integrity is mocked, Noah’s example offers quiet encouragement. He did not withdraw from his world or pretend it was healthy, yet he kept walking with God and listening to his voice. Building an ark in front of a skeptical crowd would have been a lonely task, and most of us face smaller versions of that loneliness when we choose faithfulness.

Lord, you see the state of our world and the thoughts of our hearts more clearly than we ever could. Some days the wickedness around us feels overwhelming, and I confess that my own heart is not always as clean as I would like. Thank you that you do not turn away from what grieves you, and thank you that you still look for people who will walk with you. Make me a person of quiet faithfulness, willing to do what you ask even when the path seems strange. Let your grace be as real in my life as it was in Noah’s, and keep me close to you. Amen.
