Genesis 6:3 says that God’s Spirit will not keep striving with humanity indefinitely, and that human life will be limited to 120 years. God speaks this word in response to spreading wickedness before the flood, and it is addressed to himself as an announcement of how he will deal with a corrupted world. The verse is less a rule about lifespan than a statement about divine patience reaching a boundary.
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.”

What Genesis 6:3 Means
The phrase “my Spirit will not strive with man forever” uses a word meaning to contend, judge, or remain in a dispute. The image is of God’s Spirit pleading with people, working to restrain their violence and turn them toward righteousness. The verse tells us that this pleading has a limit. God is patient, but he is not endlessly patient, and the time for his restraining work is coming to an end.
The reason given is “because he also is flesh.” Human beings are mortal and frail, made of the same material as the ground they came from, and they are not divine. So God sets a fixed span of days, here understood as 120 years, as the boundary within which people will live before judgment falls. The verse does not promise a long life to anyone, and it does not explain every later lifespan in Scripture. It describes God’s decision about how long his patience will hold in that generation.
The Context of Genesis 6:3
Genesis is traditionally attributed to Moses, and it was written to a people who needed to understand where they came from and who God is. The book begins with creation and then traces the human story through the fall, Cain and Abel, and the growth of sin. Chapter 6 marks a turning point, as the earth fills with violence and “every imagination of the thoughts of man’s heart was continually only evil” (verse 5). Verses 1 and 2 describe a mixing of divine and human that signals a corruption of God’s created order.
Read alongside verses 5 and 6, verse 3 is not a random notice about human age. It is part of God’s response to a world that has grown deeply wicked, and it shows his grief as well as his justice. The limit on days is a sign of mercy that will soon give way to judgment. The verse makes more sense when you see it as the last window of patience before the flood narrative begins.

Paul writes about God’s kindness, patience, and forbearance as a reason to repent rather than to presume on his mercy. Like Genesis 6:3, this passage holds together God’s patience and the serious call to turn back before the day of judgment.

7 Therefore, even as the Holy Spirit says, “Today if you will hear his voice, 8 don’t harden your hearts, as in the rebellion, like as in the day of the trial in the wilderness…
