A Generation of Vipers: Who Are the Children of the Wicked One?

Based on Bible Mysteries Podcast Episode 298: A Generation of Vipers: Serpent Seed or Spiritual Rebellion?

Jesus used some of His strongest language when speaking to the religious leaders of His day. John the Baptist did the same.

In Matthew 3:7, John saw the Pharisees and Sadducees coming to his baptism and

declared:

“O generation of vipers, who hath warned you to flee from the wrath to come?”

Later, Jesus used nearly identical words:

“O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.” — Matthew 12:34

Why call them vipers? Was Jesus identifying a literal serpent bloodline, or was He revealing their spiritual allegiance?

That question becomes even more intriguing when Jesus describes the tares in Matthew 13 as the children of the wicked one.

When these passages are considered together, a pattern emerges. Scripture repeatedly connects unbelief, corrupt words, evil fruit, false religion, and rejection of God's Word with those who spiritually identify with the adversary.

Who Are the Children of the Wicked One?

In the parable of the wheat and tares, Jesus explains exactly what the symbols represent:

“The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one; The enemy that sowed them is the devil.” — Matthew 13:38–39

Jesus identifies two groups: the children of the kingdom and the children of the wicked one.

The tares are particularly significant because they grow among the wheat. A tare can resemble wheat for much of its growth. The difference becomes apparent when the plants produce fruit.

This fits perfectly with something Jesus had already taught:

“Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by his fruit.” — Matthew 12:33

The distinction is ultimately revealed by the fruit.

The Children of the Wicked One Are Known by Their Fruit

John the Baptist made the same connection when confronting the generation of vipers:

“Bring forth therefore fruits meet for repentance.” — Matthew 3:8

He then warned:

“And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire.” — Matthew 3:10

Notice the pattern: vipers, fruit, trees, and judgment.

Jesus continues this same imagery in Matthew 12. Immediately before calling the Pharisees a generation of vipers, He speaks of good trees and corrupt trees.

Their outward religious appearance was not the determining factor. Their fruit

revealed what was in their hearts.

What Does Generation of Vipers Really Mean?

The Greek phrase translated “generation of vipers” is genēma echidnōn.

Genēma refers to that which has been born or begotten—offspring or progeny. Echidna means a viper and can also be applied figuratively to cunning, malignant, or wicked men.

This naturally raises the question of whether Jesus and John were speaking about physical lineage.

Yet the context points us toward something else.

When John calls the Pharisees and Sadducees a generation of vipers, he immediately commands them to repent and bring forth appropriate fruit. He also addresses their claim of physical descent:

“And think not to say within yourselves, We have Abraham to our father...” — Matthew 3:9

Their genealogy from Abraham did not make them righteous.

The issue was their heart, their unbelief, and the fruit they produced.

An Evil Generation Is Defined by Unbelief

The Bible uses the word “generation” in ways that do not require a genetic interpretation.

Consider the Israelites who refused to enter the Promised Land because they feared the giants.

God said:

“And the LORD heard the voice of your words, and was wroth, and sware, saying, Surely there shall not one of these men of this evil generation see that good land...” — Deuteronomy 1:34–35

These were Israelites. Yet God called them an “evil generation.”

Why?

Unbelief.

They refused to believe what God had said. And notice what God heard: “the voice of your words.”

That same connection between the heart and the mouth appears when Jesus confronts the generation of vipers.

“For out of the abundance of the heart the mouth speaketh.” — Matthew 12:34

Their words revealed their unbelief.

Words Reveal Spiritual Allegiance

Jesus continues:

“For by thy words thou shalt be justified, and by thy words thou shalt be condemned.” — Matthew 12:37

Psalm 12 presents a similar contrast.

The wicked speak vanity and flattering words. They boast:

“With our tongue will we prevail; our lips are our own: who is lord over us?” — Psalm 12:4

Then Scripture immediately contrasts man's corrupt speech with God's words:

“The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times.” — Psalm 12:6

There has always been a battle over God's Word.

And that battle began with the serpent.

The Children of the Wicked One Follow the Serpent's Pattern

The first recorded words of the serpent are significant:

“Yea, hath God said...” — Genesis 3:1

First, the serpent questioned God's Word.

Then he contradicted it:

“Ye shall not surely die.” — Genesis 3:4

Question the Word. Contradict the Word. Replace God's truth with a lie.

Jesus identifies the same pattern when speaking to the religious leaders:

“Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning... for he is a liar, and the father of it.” — John 8:44

These men possessed the Scriptures. They were religious leaders. Yet when the living Word stood before them, they rejected Him.

Their religion did not prove who their father was.

Their response to the truth did.

Does Your Father the Devil Mean Serpent DNA?

It is tempting to read Jesus' words as a statement about genetics. Considering Genesis 6, the Nephilim, and other passages involving supernatural interference with mankind, the question is understandable.

But we should be careful not to state as fact what Scripture does not explicitly establish.

When a person believes the gospel, that person becomes a child of God:

“But as many as received him, to them gave he power to become the sons of God...” — John 1:12

That does not mean the believer's physical DNA immediately changes.

It is a spiritual identification.

In the same way, when Jesus tells the Pharisees that their father is the devil, the context emphasizes their rejection of truth, their lies, their murderous intentions, and their unbelief.

What identifies them with the serpent is their spiritual allegiance.

Cain and the Children of the Wicked One

This pattern can be traced all the way back to Cain.

Cain was not an atheist. He brought an offering to the Lord:

“And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD.” — Genesis 4:3

Cain was religious.

But Cain approached God according to his own way rather than God's way.

Jude later warns about those who have:

“gone in the way of Cain...” — Jude 11

This is false religion in its earliest form—acknowledging God while refusing to submit to Him.

Cain wanted worship on his terms.

False Religion Can Look Like the Truth

Jude describes false brethren with striking tree imagery:

“Trees whose fruit withereth, without fruit, twice dead, plucked up by the roots.” — Jude 12

Again we find trees and fruit.

Jesus warned about corrupt trees.

John warned that fruitless trees would be cut down.

Jude describes false brethren as trees without fruit.

And Jesus describes the children of the wicked one as tares growing among wheat.

The warning is difficult to miss: false religion can exist alongside true faith and outwardly resemble it.

The fruit eventually reveals the difference.

From Cain to the Generation of Vipers

Jesus makes an extraordinary connection in Matthew 23.

Speaking to the scribes and Pharisees, He says:

“Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.” — Matthew 23:31

Then He declares:

“Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?” — Matthew 23:33

Jesus traces the shedding of righteous blood all the way back to Abel:

“That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel...” — Matthew 23:35

Who killed Abel?

Cain.

Cain was religious. The Pharisees were religious. Both rejected God's way while maintaining an outward form of worship.

The generation of vipers follows the way of Cain.

The Children of the Wicked One Remain Until the Harvest

Jesus does not say the tares disappear before the end.

They remain among the wheat until harvest.

“Let both grow together until the harvest...” — Matthew 13:30

When Jesus explains the parable, He tells us when that harvest occurs:

“The harvest is the end of the world; and the reapers are the angels.” — Matthew 13:39

That means the conflict between true faith and false religion continues throughout the age.

There will be wheat.

There will be tares.

There will be those who believe God's Word and those who question, contradict, and corrupt it.

And outward appearance alone will not always reveal the difference.

Fruit will.

The Generation of Vipers and the Days of Noah

This also gives us something important to consider concerning the days of Noah.

Genesis 6 clearly records supernatural corruption involving the sons of God and the daughters of men. The Nephilim were present, and the earth was filled with wickedness.

But Scripture does not explicitly state that every human being outside Noah's family had become genetically corrupted.

Genesis 7:1 says:

“Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.”

The Hebrew word translated “generation” here is dor, which can refer to an age or period of time. It does not require us to conclude that the statement concerns genetics.

There may have been people in Noah's day who were fully human yet spiritually aligned with evil, just as there are today.

That distinction matters because Jesus specifically points us back to Noah when discussing His return.

“And as it was in the days of Noe, so shall it be also in the days of the Son of man.” — Luke 17:26

Daniel 2:43 also raises intriguing questions about the last days:

“They shall mingle themselves with the seed of men...”

Could there again be a genetic component to satanic corruption? Possibly. The passage certainly gives us reason to ask the question.

But where Scripture stops, we should stop.

What Defines the Children of the Wicked One?

When we allow Scripture to define its own terms, a consistent picture emerges.

The children of the wicked one reject God's truth while often maintaining an outward religious appearance. They follow the serpent's pattern of questioning and contradicting God's Word. They walk in the way of Cain by approaching God on their own terms. Their words expose what is in their hearts, and their corrupt fruit eventually reveals the nature of the tree.

That is why Jesus could look at respected religious leaders and say:

“O generation of vipers, how can ye, being evil, speak good things?” — Matthew 12:34

The generation of vipers is not identified merely by physical ancestry. Scripture's emphasis is spiritual.

Who do they believe?

Whose words do they follow?

What fruit do they produce?

The tares are among the wheat. The false can resemble the true. Religion itself is not proof of righteousness.

Jesus gave us the test:

“For the tree is known by his fruit.” — Matthew 12:33

The children of the wicked one ultimately reveal their father by rejecting Christ, opposing God's Word, producing corrupt fruit, and following the pattern of rebellion that began with the serpent.

The question is not simply what someone claims to believe.

The question is: What does the fruit reveal?
