The Flood narrative stands as one of the most familiar yet profound stories in the Bible. Found in Genesis chapters 6–9, it reveals God’s response to humanity’s sin, His salvation for the faithful, and His enduring mercy toward all creation.

A World Corrupt and Broken

The story begins with a world utterly corrupted by sin:

Now the earth was corrupt in God’s sight and was full of violence. 12 God saw how corrupt the earth had become, for all the people on earth had corrupted their ways. 13 So God said to Noah, “I am going to put an end to all people, for the earth is filled with violence because of them. I am surely going to destroy both them and the earth.

Genesis 6:11-13

Human wickedness had reached such depths that God resolved to judge the earth with a flood. Yet even in this judgment, God’s grace shines through — for Noah found favor in the eyes of the Lord.

Noah: The Righteous Man

God gave Noah specific instructions:

14 So make yourself an ark of cypress[a] wood; make rooms in it and coat it with pitch inside and out. 15 This is how you are to build it: The ark is to be three hundred cubits long, fifty cubits wide and thirty cubits high.[b] 16 Make a roof for it, leaving below the roof an opening one cubit[c] high all around.[d] Put a door in the side of the ark and make lower, middle and upper decks. 17 I am going to bring floodwaters on the earth to destroy all life under the heavens, every creature that has the breath of life in it. Everything on earth will perish. 18 But I will establish my covenant with you, and you will enter the ark—you and your sons and your wife and your sons’ wives with you.

Genesis 6:14-18 NIV

Noah obeyed exactly as God commanded, assembling the ark, taking the animals, and preparing for what lay ahead.

The Flood Begins

At the appointed time, God’s judgment unfolded:

11 In the six hundredth year of Noah’s life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened. 12 And rain fell on the earth forty days and forty nights.

Genesis 7:11-12 NIV

Noah, his family, and pairs of every kind of animal entered the ark.

The Waters Cover the Earth

17 For forty days the flood kept coming on the earth, and as the waters increased they lifted the ark high above the earth. 18 The waters rose and increased greatly on the earth, and the ark floated on the surface of the water. 19 They rose greatly on the earth, and all the high mountains under the entire heavens were covered. 20 The waters rose and covered the mountains to a depth of more than fifteen cubits. 21 Every living thing that moved on land perished—birds, livestock, wild animals, all the creatures that swarm over the earth, and all mankind. 22 Everything on dry land that had the breath of life in its nostrils died. 23 Every living thing on the face of the earth was wiped out; people and animals and the creatures that move along the ground and the birds were wiped from the earth. Only Noah was left, and those with him in the ark.

Genesis 7:17-23 NIV

The Waters Recede

After months in the ark, God remembered Noah:

8 But God remembered Noah and all the wild animals and the livestock that were with him in the ark, and he sent a wind over the earth, and the waters receded.

Genesis 8:1 NIV

The ark came to rest on the mountains of Ararat, and eventually the earth dried. Noah and all aboard were released onto a new world.

A New Beginning

20 Then Noah built an altar to the Lord and, taking some of all the clean animals and clean birds, he sacrificed burnt offerings on it.

Genesis 8:20 NIV

God’s Covenant With All Creation

God then made a remarkable promise:

11 I establish my covenant with you: Never again will all life be destroyed by the waters of a flood; never again will there be a flood to destroy the earth.”

Genesis 9:11 NIV

And God gave a sign of this covenant:

13 I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. 14 Whenever I bring clouds over the earth and the rainbow appears in the clouds, 15 I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life. 16 Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of every kind on the earth.”

Genesis 9:13-16 NIV

The rainbow stands today as a sign of God’s covenant with Noah, his descendants, and every living creature.
