Genesis 6:1-4 is one of the most debated passages in the Bible.
It describes a time before the flood when the “sons of God” took wives from the “daughters of men,” and their offspring became “mighty men of old, men of renown.”
Some believe this passage refers to fallen angels interbreeding with human women to produce half-demon giants known as the Nephilim.
However, a closer examination of Scripture suggests a more rational explanation.

Why People Believe the Sons of God Are Angels
The belief that the “sons of God” in Genesis 6 refers to fallen angels stems from the phrase “sons of God” appearing in Job 38:7, where it refers to angelic beings.
Additionally, ancient Jewish and extra-biblical traditions propose that angels mated with humans, resulting in supernatural offspring.
However, there are several strong biblical reasons why this interpretation is flawed.
Reasons Why the Sons of God Are Not Angels
If we take a deep look at what the Bible says, we can clearly conclude that the sons of God mentioned in Genesis 6 are not angels or any spirit beings.
Instead, the sons of God are human beings.
Here are some important reasons to consider:
1. Angels Do Not Marry or Reproduce
Jesus Himself taught that angels do not marry or engage in sexual relations (Luke 20:34-36).
They are spiritual beings, not physical creatures, making it impossible for them to reproduce with human women.
2. God Was Angry with Humans, Not Angels
In Genesis 6:3 and 6:7, God’s judgment is directed at humanity, not angels.
If fallen angels were the primary culprits, one would expect God’s punishment to be focused on them rather than solely on mankind.
3. The Bible Says That Living Beings Reproduce After Their Own Kind
Genesis 1 repeatedly states that every creature reproduces “according to its kind.” This principle contradicts the idea that angels, which are spiritual beings, could produce offspring with humans, who are physical beings.

Who Are the Sons of God?
While we cannot be 100% certain about the identity of the “sons of God” in Genesis 6, we can be absolutely sure they are not angels. Given this, who might they be? Here are several plausible explanations:
1. Sons of God Refers to Wicked People Taking the Righteous Title
Some believe the “sons of God” were powerful rulers or men who claimed divine status, as was common in ancient civilizations where kings were considered gods or demigods.
2. Sons of God Refers to the Descendants of Righteous Seth
Another common interpretation is that the “sons of God” were the descendants of Seth, the righteous line of Adam. These godly men intermarried with the ungodly descendants of Cain, leading to widespread moral corruption and wickedness.
3. Sons of God Refers to Righteous People Who Turned Away from God
Another possibility is that the “sons of God” were originally faithful followers of Yahweh who later rebelled and engaged in sinful behavior, leading to the downfall of society.
4. The “Sons of God” Represented Generally Evil Men
The term could broadly refer to men who were powerful, influential, and corrupt, acting in defiance of God’s ways. They may have forcefully taken wives, oppressing others in their pursuit of power and pleasure.
Who Were the Nephilim or Giants in Genesis 6?
Many people believe the Nephilim were a race of gigantic superhuman beings resulting from the union of angels and humans. However, a careful reading of Genesis 6:4 tells us otherwise:
“There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.”
This verse indicates that the Nephilim already existed before these marriages took place, meaning the unions did not produce them. The Hebrew word translated as “giants” is Nephilim, which can refer to size but also to character. Here are key points about the Nephilim:
- The root word for Nephilim is naphal, which means “fallen,” often associated with a fallen or violent nature.
- Nephilim can also mean “tyrants” or “bullies,” suggesting these were powerful, oppressive individuals rather than supernatural giants.
- The phrase “mighty men” in Genesis 6:4 refers to warriors or rulers known for their exploits, not necessarily their physical stature.
- Some biblical commentators suggest that these Nephilim were warlords or despots who gained renown through violence and oppression.
The idea that God was punishing the world because of physical giants is unlikely. Instead, He was condemning the rampant wickedness and corruption of mankind, particularly among these mighty and oppressive men.

Lessons from Genesis 6:1-4
- Righteousness Can Be Corrupted – The passage warns about the dangers of mingling righteousness with wickedness. When godly people associate too closely with sin, it can lead to moral decay.
- God’s Judgment Is Just – The flood was a result of humanity’s persistent wickedness. This reminds us that God is patient but will ultimately judge sin.
- God’s Plan Remains Unshaken – Despite humanity’s corruption, God’s plan of redemption continued through Noah and his descendants, showing that He remains sovereign and faithful.
Genesis 6:1-4 is not about angels interbreeding with humans but about the increasing wickedness of mankind leading up to the flood. The passage serves as a powerful reminder of the importance of remaining faithful to God and avoiding the corrupting influence of sin.
