Consider the parallels in the long table in this post. It reveals who we are. God’s gigantic global project for us humans is to lift us out of our sin-mammal nature and recover the image of God in Christ.
There are two theories as to how we have our sin nature. One is that it is imputed to us from Adam, by virtue of his being our federal head. The second is that it is imparted to us from our parents through genetics, from Adam (or humankind) to now. Sin is in our genes.
This post explores the second theory with additional information.
At the time of this posting, I teach at a community college, and I have found that the best way to help students see a higher vision for their lives is to draw parallels between nonhuman mammals and human mammals, and then call them to live higher, to develop their souls. Science teaches students that they are mammals, and they will not deny science in favor of a skewed and mistaught version of Christianity that denies the obvious. Nor should they deny science, when it is so clear and correct on this topic. Humans belong in the mammal category. Then, when I spell out for them the numerous parallels, light bulbs in their eyes go off all over the room. They see themselves as they really are. They can change. They can aim higher. They have hope.
In this post, I go further than what I can say in the state-run classroom and discuss the fractured image of God in all of us humans, and how God’s goal is to restore his image in us.
Just take this post for what it is: a tentative, exploratory musing.

Image of God in humans
The Bible says we are made in God’s image (Gen. 1:26-27; Gen. 9:6).
One more time for emphasis and clarity:
Humans are made in the image of God.
Yet science says and our own experience proves that we are mammals.
We fit the classic definition: “A warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, females that secrete milk for the nourishment of the young, and (typically) the birth of live young” (Source).
1.. All humans are mammals.
2.. You and I are humans.
3.. Therefore, you and I are mammals.
Does Scripture support the fact that we are mammals?
Let me letter the main points of Scripture for clarity and conciseness.
A.. Gen. 2:7 says God formed humankind (’adam) from the dust of the ground, and Gen. 2:18 says God formed all the wild animals and birds out of the ground. Whether you take those two verses literally or figuratively, they teach that humans and mammals are made of the same substance.
B.. The Hebrew noun zakar (pronounced zah-kahr) means “male” in contrast to the generic “man” (used 82 times). It can refer to male offspring of humans (Lev. 12:2; Is. 66:7; Jer. 20:15) and animals (Exod. 12:5; Lev. 1:3, 10; 22:19).
C.. The Hebrew noun for soul or life or consciousness is nephesh (used 757 times), and both animals and humans can have it (Gen. 1:20-21, 24, 30; 2:7, 19; 9:4, 10, 12, 15, 16). Even the Revelation says that creatures of the sea have “life” (Rev. 8:8; 16:13).
D.. The sons of Korah have this apt comparison: “People who have wealth but lack understanding are like the beasts that perish.” (Ps. 49:20)
E.. The psalmist compares his enemies to prowling and howling pack of dogs in Jerusalem:
14 They return at evening,
snarling like dogs,
and prowl about the city.
15 They wander about for food
and howl if not satisfied. (Ps. 59:14-15)
F.. The psalmist sees himself as a brute beast, when he had lacked wisdom: “I was senseless and ignorant; I was a brute beast before you” (Ps. 73:22)
G.. When the wise man Agur thought he lacked human understanding, he described himself in this way: “Surely I am only a brute, not a man; I do not have human understanding” (Prov. 30:2).
H.. In Solomon’s opinion, he wrote: “As for humans, God tests them so that they may see that they are like the animals” (Eccl. 3:18).
I.. Jeremiah compares the lust in humans to she-camels in heat offering themselves to he-camels and wild donkeys looking to breed (Jer. 2:23-24). The prophet also compares humans with the “lust” in horses: “They are well-fed, lusty stallions, each neighing for another man’s wife” (Jer. 5:8; 13:27). He saw the similarities in the breeding lust between humans and non-human mammals.
J.. Jerusalem is compared to a lusty woman in stark, mammalian terms: “There she lusted after her lovers, whose genitals were like those of donkeys and whose emission was like that of horses.” (Ezek. 23:20).
Some could object that those verses in the OT are metaphors and similes, which must not be taken literally. In reply, those metaphors and similes reveal the parallels between humans and nonhuman mammals, comparisons that cannot be easily written off.
Now let’s more to the New Covenant Scriptures, where everything is upbeat and positive–or is it?
A.. Paul warned Titus that Cretans can fall into their baser nature: “One of Crete’s own prophets has said it: “Cretans are always liars, evil brutes, lazy gluttons.” (Titus 1:12)
B.. Peter writes that degraded humans are irrational animals, born with natural instincts: “… They are like unreasoning animals, creatures of instinct, born only to be caught and destroyed, and like animals they too will perish” (2 Pet. 2:12). Then he goes on to compare them to dogs that return to their vomit, and washed sows that go back to wallowing in mud (v. 22).
C.. Jude also says that humans outside of life in the Spirit follow “mere natural instincts”: “and the very things they do understand by instinct—as irrational animals do—will destroy them” (v. 10). And “these are the people who divide you, who follow mere natural instincts and do not have the Spirit” (v. 19)
D.. Scripture often compares human mammals to sheep (Ezek. 34:11-12, 15; Matt. 9:36; 10:6; 18:12-13).
E.. The Greek word for physical “flesh” is sarx (used 147 times), though there may be differences in the flesh of one mammal to the next (1 Cor. 15:39). In some contexts, it is sometimes translated as “sin nature” because the contexts warrant it (Rom. 6:6:19; 7:5; 18, 25; 8:3-9, 12-13; Gal. 5:16-19). So it could be that the biblical authors saw that the sin nature resides in the flesh, perhaps the brain or the “heart” and body, where our internal nature is expressed outwardly.
F.. The Greek word for “body” is sōma (used 142 times), and it can be used of humans and animals (Jas. 3:3; Matt. 5:29; 6:22; 26:12).
G.. Paul writes that our earthly nature is the source of our urges to do wrong. “Put to death, … therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry” (Col. 3:5). The Greek literally reads, “on the earth,” so our earthly body has some defects.
H.. Here is a sample verse that connects the flesh and the body with sin: “For if you live according to the flesh (sarx), you will die, but if by the Spirit you put to death the misdeeds of the body (sōma), you will live” (Rom. 8:13).
Now let’s apply these biblical data.
Parallels between nonhuman and human mammals and then God’s higher calling
This table shows the parallels between nonhuman mammals and humans and bad behavior and most importantly how God calls humans to restore his image and follow his higher calling to have souls filled with righteousness.
The clearest and most direct way to change the human condition is biblical revelation, the third column.

|Mammals can get addicted to drugs and nicotine and alcohol if fed to them, and they do not know how to stop. Chimps can learn to be chain smokers (and so on).||Some people can also get addicted to those things and find it difficult to break the habit. They can become chain smokers (and so on).||Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit (Eph. 5:18); older women [are …] not to be … addicted to much wine (Tit. 2:2).|
|Males and females attract.||Males and females attract, can turn into lust. (Attraction is not sinful, but lust is.)||But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart (Mt. 5:28).|
|Some mammals seem to be attracted to same sex.||Some people are attracted to same sex.||Neither the sexually immoral … nor men who have sex with men … will inherit the kingdom of God … And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God (1 Cor. 6:9-10).|
|Alpha male claims many females.||“Alpha” male desires sex with many females; one religion endorses polygamy for rich male, the alpha, the “top dog.”||At the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’? (Matt. 19:4-5)
|Eager to show they are the alphas, males fight for right to breed.||Climbing to top, some males fight (sometimes fist-fight) to show they are alpha male, for right to breed.||Jesus called them together and said, “You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them.

Instead, whoever wants to become great among you must be your servant, and whoever wants to be first must be your slave— just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many” (Mt. 20:25-28).|
|Some female chimps trade sex for food.||Some females sell their bodies for money.||Jesus said to them, “Truly I tell you, the tax collectors and the prostitutes are entering the kingdom of God ahead of you. For John came to you to show you the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes did. And even after you saw this, you did not repent and believe him (Mt. 21:31a-32).|

|Males are less discriminating in breeding.||Males are less discriminating in breeding (males visit brothels much more often than females do, if at all).||Should a man take his body, which is part of Christ, and join it to a prostitute? Never! (1 Cor. 6:15, NLT).|
|Mammals seem to eat almost nonstop.||Some people eat too much (gluttony).||Do not join those who drink too much wine or gorge themselves on meat, for drunkards and gluttons become poor, and drowsiness clothes them in rags (Prov. 22:20-21).|
The above table shows that God’s global project is to lift humans out of their mammal / sin nature and restore his image in them.
Further, our mammal nature may equal human sin nature, in part. At the very least our sin nature is embedded in our mammal nature, in part. If this is true, then it argues for the theology that says that original sin / mammal nature is inherited from human parents to offspring; they pass it along to children. The doctrine of original sin is sustained.
Some similarities between nonhuman mammals and human mammals are neutral.
Nonhuman females are attracted to an alpha male; human females are attracted to a human alpha male (an athlete, for example). But human females better include good character in their calculations.
Female primate gestures and postures to show sexual availability; woman gestures and postures to show sexual availability.
Sex hormones influence desire to breed; sex hormones influence desire to breed. (Sex in marriage is not sinful.)
Some mammals sometimes do good things, like a dog showing loyalty to its owner or the alpha male, the leader of the pack. Dogs have sacrificed their lives to save their human alphas or pack members.
A TV animal documentary about a herd of elk showed that one was wounded, and another one stayed with it and chased off a lone wolf.
So nonhuman mammals and human mammals can do both bad and good actions. That’s why I need to add that our mammal nature is our sin nature in part.
Questions and answers
1.. Does the sinful mammal nature permeate the soul and spirit of a human?
Some teachers claim that the human spirit, when it is born again, remains sinless. However, we are a unit, whether you believe in a body, soul and spirit, or just a body and soul. Sin defiles the whole person.
2.. Do human mammals have souls?
Yes, of course, they do. The Bible affirms it everywhere, as I noted in the Scripture section. And if you believe in three parts of the human (spirit, soul, body), then each human mammal has a spirit, too. Don’t be thrown off by the word mammal. It’s just human nature, looked at from a different angle—our connection to nonhuman mammals, a well-established fact.
3.. Do nonhuman mammals have souls?
Not in the sense and to the depth that humans have soul. Both share nephesh, however.
4.. Doesn’t the Bible say we are much more valuable than nonhuman mammals (Matt. 12:12)? Are you saying that humans are merely mammals?
No, of course not. We are made in the image of God (note the emphasis in red font in the introduction). Other mammals are not. We are of a higher order than nonhuman mammals. Our spirits-souls can communicate with God and look up to him. One theologian called us homo divinus (divine man) for that reason. But we’re talking about our sin nature in this post, and our sin nature comes from our mammal nature. Indeed, our sin nature resides in our mammal nature.
5.. Are you saying nonhuman mammals sin?
This may be a category mistake in applying guilt and sin to nonhuman animals. But sometimes they seem to exhibit a conscience, when a dog kills a chicken and looks guilty. Koko the gorilla blamed her pet kitten for damaging items in her enclosure during the night. That was a lie. Did she know it was a lie?
6.. How does Adam fit into the picture?
See my post 3. Adam and Evolution: Five Options
7.. So are you saying that we do not inherit sin nature from Adam?
Humanity did, if you translate Adam as his name really means: humankind. After all, the Hebrew noun ’adam is used 558 times in the Hebrew Bible, and it means humanity as a whole: men, women, children together. Only 12 times does it seem to signify the proper name Adam (Gen. 3:17; 3:20-21 [2x]; 4:1, 25; 5:1-5 [4x]; 1 Chron. 1:1 and Hos. 6:7).
So it is best to translate Adam as “humankind.”
Therefore, yes, we inherit original sin from our human / mammal nature and our broken relationship with God, and this fractured nature is passed on from one generation to the next. Sin is rooted deeply in human origins and human nature. We inherit it from humankind, because we are humankind. We are trapped in our own closed human circuit.
8.. So do humans have free will?
The answer is the same whether we say “mammal nature” or “sin nature.” They have it to a significant degree, and they must deny their sinful nature that is embedded in their mammal nature and exercise their free will to live righteously.
9.. What does this mean for the doctrine of original sin?
As noted (no. 7), the first option of the doctrine of original sin is sustained, if my thesis is true. Our sin nature flows out our mammal nature because our sin nature is embedded in our mammal nature.
10.. Where does the Fall come in?
The Fall is just one interpretation of Gen. 3, but if you must have this interpretation, then here it is: All human mammals “have sinned and fallen short of the glory of God” (Rom. 3:23). At some time in the primeval past humans fell short, though God’s original intention was for humans to know him intimately. Paul said that primitive humankind knew God, but fell away from or rejected or refused to glorify God (Rom. 1:21). That is a great description of a fall of some kind.
All humans are deficient in their saving knowledge of God, because an unbridgeable gap stands between them and God’s glory, until God bridges the gap through Christ. That’s our “Fall” and our later redemption.
11.. What does your tentative, exploratory thesis say about Paul’s theology in Romans 5:12-21?
If we translate “Adam” as “humankind,” then Paul’s thesis is sustained: through humankind all sin and trespass and death entered the world. Death and sin are built in to humankind’s human / mammal nature. Admittedly, this may make the more restrictive Bible interprets nervous, but I hope they will think about the exploratory thesis in this post. It solves more problems than poses.
Finally, no fear! Just because I use the word mammal does not change the entire structure of theology through and through. The word should not be scary to Christians, because they should not be afraid of scientific facts. This tentative, exploratory thesis of our mammal nature has sustained the Bible description of human sin and Paul’s argument, but with minor adjustments. These small adjustments are not a too high a price to pay for reasonable believers.
The Bible’s description of human nature is still accurate and still stands. The doctrine of original sin stands.
How does this post help me grow in Jesus?
When humans desire to be in an intimate relationship with God and to be with him in heaven, their mammal / sin nature cannot lead them to the right way. How does this intimacy happen?
They need to go through Christ. “And have put on the new self, which is being renewed in knowledge in the image of its Creator” (Col. 3:10).
Humans need redemption and salvation to rise above their pure mammal nature, their incomplete and fractured souls. God calls all humans to be redeemed and leave behind their pure mammal nature. How?
Sanctification is a process to walk in holiness and righteousness. God’s Spirit lives in each human who calls on him in Jesus’s name, in order to be restored from brokenness caused by the mammal / sin nature and decisions flowing out of our moral blindness (we don’t realize we have a mammal nature that leads us astray).
God’s big global project for humanity, therefore, is to lift humans out of their mammal / sin nature and restore the image of God in them, through a personal relationship with him through Christ and by the indwelling Holy Spirit.
Finally, church father Irenaeus (flourished 175-195) said, “The glory of God is man fully alive.” When we consider that God’s big global project is to redeem humanity out of its mammal nature and restore the broken image of God, then Irenaeus’s statement is true. God is calling you, whether a believer or unbeliever, to know him better with saving faith and the indwelling of the Holy Spirit. Then you really are the glory of God because you are fully alive in Christ.
