What does Genesis 6:13 mean?
God begins revealing His plan to Noah. We can only assume it must have been devastating for Noah to hear. As a righteous, blameless man who walked with God (v. 9), Noah would likely have agreed that the earth was filled with violence because of the sinfulness of humanity. But could anything have prepared Him for God's announcement? We can't be entirely sure about how many relatives, including possibly other children, Noah had at this time. Regardless, the idea of the entire human world being killed would have been terrifying.In plain language, God told Noah that He was getting ready to put an end to all of humanity because of their violence. He would destroy "all flesh," meaning both humanity and animals, along with the earth—or land—itself. In one blunt statement, God announces to Noah both His verdict and the sentence on humanity. God would exercise His right as creator and judge; He would hold His creatures responsible for their sinful choices. He alone had (and still has) both the right and the power to carry out such a plan.
Genesis 6:9-22 begins another new section in Genesis called the ''generations of Noah.'' Because of humanity's power and wickedness, the earth had become filled with violence and sinfulness. By contrast, Noah was a righteous, blameless man who walked with God. God chooses to declare to Noah His plan to end all land-dwelling life on earth, but also to save Noah and his family and two of every animal. Noah obeys God's command to build the ark that would preserve the human race from total destruction in the flood.
God sees. In the first chapter of Genesis, God saw that all He had made was good. Now, many generations after sin entered the world, God sees that all man has made is wickedness and evil. Human beings have used their power for violence and destruction. God declares His plan to wipe out all land-dwelling life on the face of the earth. He will however, preserve humanity and animal life for a new beginning through the one righteous man, Noah, and a huge life-giving structure called an ark.
