Genesis 6:5 describes how far human wickedness had spread before the flood: God looked at the earth and saw that people were constantly inclined toward evil in their inner thoughts. The verse explains why God then acts in judgment, and it is recorded by Moses as narrator of the early history of the world, written for the people of Israel who were learning how the Creator dealt with sin.
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.

What Genesis 6:5 Means
The verse begins with God “seeing,” which means He observes the actual condition of the world rather than a distorted picture. What He sees is that human wickedness had grown large across the whole earth, not just in a few places. The phrase “every imagination of the thoughts of man’s heart” points to the inner life, the plans, desires and motives that form before any action is taken. The writer says this inward bent was “continually only evil,” meaning it was not occasional or mixed but persistent and one-directional.
The verse explains the reason behind God’s coming judgment in the story, but it does not describe every individual in exactly the same way, since the next verses single out Noah as someone who found favor. It also does not teach that humans can do nothing good at all, because other parts of Scripture speak of genuine righteousness. What it does show is the depth of the problem as God sees it: the trouble lies in the heart, not merely in outward behavior.
The Context of Genesis 6:5
Genesis is the first book of the Torah, traditionally attributed to Moses, and it sets the stage for the whole biblical story by showing creation, the fall into sin, and the spreading consequences of that rebellion. Chapter 6 opens with troubling relationships between divine beings and human women and the rise of violent figures, which signals a world moving further from God’s design. Verse 5 sits at the center of this description, giving the reason for what follows.
Just after the verse, we read that God regrets making humanity and resolves to destroy the earth’s living things, yet Noah finds favor in His eyes. That turn matters for reading the verse well, because it shows that the diagnosis of universal evil is followed immediately by grace toward one man. The verse is therefore not the last word on human nature in this story but the backdrop that makes God’s mercy toward Noah stand out.

A Short Prayer From Genesis 6:5
Lord, you see the inner places of my life more clearly than I do, and you know the thoughts I would rather keep hidden. I confess the patterns in my heart that pull me toward what is wrong, and I ask you to search me and show me where I need to change. Create in me a clean heart and renew a steadfast spirit within me. Thank you that you do not turn away from honest hearts, and that your mercy is greater than the sin you see. Help me to bring my thoughts to you each day. Amen.
