Spirit, Soul, and Body: What Do They Mean?

What Scripture Means by Spirit

Paul gives us a good place to begin in 1 Corinthians 2:10–16. He speaks about the Spirit of God knowing the depths of God, the human spirit knowing what is within a person, and believers receiving the Spirit who is from God. Then he contrasts that with the “spirit of the world” and ends by saying, “we have the mind of Christ.”

That language immediately tells us that spirit is not always describing a ghostly being. Paul can speak of the Spirit of God, the spirit of a person, and the spirit of the world within the same argument. Context tells us what he means.

What is the “spirit of the world” in that passage? It is the world’s wisdom, way of thinking, and human viewpoint apart from the Lord. Paul contrasts words taught by human wisdom with what is taught by the Spirit. The issue is how we see and understand things.

That is why I find the ordinary phrase “team spirit” useful. Nobody hears that phrase and imagines a ghost floating above the team. We understand it as a shared disposition, attitude, or way of approaching something. In these passages, spirit can carry that kind of sense as well.

The Greek word pneuma has a range of meanings. It can refer to breath or wind, a spiritual being, the Holy Spirit, or the inner disposition of a person. We do not get the meaning by picking one definition and forcing it everywhere. We get it from the passage.

In 1 Corinthians 2, Paul’s point is that the believer has received the Spirit of God and therefore has access to a way of seeing that does not come from human wisdom. That is why his conclusion about the mind of Christ matters so much. The Spirit is not merely something we possess. He brings us into a new way of seeing.

A New Heart and the Mind of Christ

That new way of seeing did not begin with Paul. Ezekiel 36:26–27 promised that the Lord would give His people a new heart and a new spirit, remove the heart of stone, give a heart of flesh, and put His own Spirit within them.

In context, Ezekiel was speaking to Israel. The hard heart of stone would be removed and replaced with a soft heart. Notice that the “heart of flesh” in Ezekiel is a good thing. That alone should warn us against assuming the word flesh always means something sinful.

The promise goes deeper than behavior. The Lord does not merely tell His people to try harder with the same inner life. He gives a new heart and a new spirit, and then He puts His Spirit within them.

Something at the core of our being had to be made new. The old person was not trained into becoming acceptable to God. That old self was crucified with Christ. We are united with Him and given new life.

This is why Christian growth is not the process of earning a better standing with the Father. We already belong to Him. Our minds are being renewed so that what we think begins to line up with what He has already made true. That is the same direction developed more fully in Renewing Your Mind in Christ.

Paul describes believers as having the mind of Christ, yet Christians can still think and act in ways that do not reflect that mind. We do not receive a fully reprogrammed brain at salvation. We grow. We learn. We discover how much of our thinking still comes from fear, pride, self-reliance, or the wisdom of the world.

The answer is not to manufacture growth. A child cannot force himself to become an adult overnight. We grow at the rate the Father works in us, and we can rest knowing that our standing with Him is settled the whole way through.

Soul, Spirit, and the Inner Person

This is where the relationship between soul and spirit becomes helpful.

In the New Testament, the word translated spirit is pneuma. According to Thayer, it can refer to “the vital principle by which the body is animated,” the rational spirit by which a person feels, thinks, and decides, and “the disposition or influence which fills and governs the soul.” In other contexts, pneuma can also refer to a movement of air, wind, or the breath of the nostrils or mouth.

The word translated soul is psuchē. Thayer describes it as the seat of the feelings, desires, affections, and aversions. In other contexts, psuchē can also refer to breath, the breath of life, the vital force that animates the body and shows itself in breathing, life itself, or a living being. Their meaning has to be read from the context in which they are used.

This is also where the ancient Hebrew way of thinking matters. It did not begin with the later Greek philosophical picture of a person divided into separate, detachable parts. The Jewish Encyclopedia, in its article “Immortality of the Soul” (1925), says that belief in the soul continuing after the dissolution of the body is a matter of philosophical and theological speculation rather than a simple truth taught in Scripture. The International Bible Encyclopedia (1960, p. 812) likewise contrasts the Greek Platonic idea that the body dies while the soul remains immortal with the ancient Israelite consciousness, saying that idea is not found in the Old Testament.

In the Old Testament, nephesh is tied to life itself. Vine’s Complete Expository Dictionary of Old and New Testament Words defines nephesh as “the essence of life, the act of breathing, taking breath.” Strong’s Exhaustive Concordance defines it as “a breathing thing,” and by extension a living creature or being of vitality. So body, soul, and spirit should not automatically be treated as three independent components inside us. They are ways Scripture can speak about one living person from different angles: bodily life, inner life, breath, thought, attitude, and the life given by God.

Spirit, as we have seen in these definitions, also carries a strong resemblance to soul in that it can refer to the breath or life of a person. We see that clearly at the cross. In Luke 23:46 Jesus cried out, “Father, into your hands I commit my spirit!” and then breathed His last. In that setting, His spirit is closely connected with His breath and life.

Soul and Spirit as a Unified Inner Life

Spirit and soul do not always carry the exact meaning of breath or life. They can also describe something deeper and more unified than separate: the inner life, thoughts, and being of the person.

Acts 4:32 says the believers were “of one heart and soul.” When they received the Spirit of God, their inner being became one with another through the attitude of the Spirit. Philippians 2:1–2 describes participation in the Spirit and then calls the church to be of the same mind, having the same love and being in full accord. Our spirit is like our inner attitude. When we have an attitude of dependence on the Father, we share the attitude Christ displayed to us in Scripture.

Paul can even tell the Corinthians that though he is absent in body, he is present “in spirit” in 1 Corinthians 5:3. He was not haunting the gathering from another city. His judgment and attitude were with them even though his body was somewhere else.

So when we speak about body soul and spirit, we need to resist the urge to turn every use of those words into a picture of three detachable objects. Scripture is often describing the whole person from different angles: bodily life, inner life, thought, attitude, breath, and the life given by God.

Understanding the Flesh

But then there is the flesh.

Like spirit and soul, flesh can take on different meanings based on context. In the New Testament the word is sarx. We need to let the context determine which meaning is being used.

Flesh as Human Nature Apart from Divine Influence

According to Thayer, sarx can mean “mere human nature, the earthly nature of man apart from divine influence, and therefore prone to sin and opposed to God.”

Romans 8:6 ESV — To set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. For the mind that is set on the flesh is hostile to God, for it does not submit to God’s law; indeed, it cannot. Those who are in the flesh cannot please God.

Galatians 5:16 — But I say, walk by the Spirit, and you will not gratify the desires of the flesh.

These are examples of sarx being used in the sense of human nature apart from divine influence. The word often has a strong connotation with the Law of Moses in that it drew Israel away from divine influence and faith, and into a mindset of self-righteous rule-keeping, worry, fear, covetousness, and the many other things that make up a sinful heart. Paul says plainly in Romans 5:20 that “the law came in to increase the trespass.” Romans 14:23 gives us the same underlying principle: “whatever does not proceed from faith is sin.”

Flesh as the Physical Body

In other contexts, according to Thayer, flesh can mean “the soft substance of the living body, which covers the bones and is permeated with blood,” as well as “the body” or “the body of a man.”

Matthew 16:17 — And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.”

Matthew 19:5 — Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh.

John 1:14 — And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.

Here flesh is referring to the human body.

Flesh as Natural Descent or Relationship

Thayer also gives another use of sarx: “natural or physical origin, generation or relationship,” or being “born of natural generation.”

Romans 1:3 — concerning his Son, who was descended from David according to the flesh

Romans 4:1 — What then shall we say was gained by Abraham, our forefather according to the flesh?

Here Paul is referring to human genealogy. We can see that the context does not describe anything related to the power of sin or the flesh as defined earlier.

The “Sinful Nature” Misconception

I have heard some grace teachers proclaim that sin indwells within us, basically that we have a sinful nature. That view was probably helped along by older editions of the NIV changing “the flesh” to “sinful nature.” It is actually an interpretation, not a translation. They tried to help us by changing “the flesh” to “sinful nature.”

The problem is that the idea of a sinful nature is not present anywhere in Scripture. It becomes even more confusing when it is applied to a Christian who is said in Scripture to have become a new creation in Christ and to partake of the divine nature. Another issue probably comes from misunderstanding Romans 7, but that is a subject for another study.

The NIV has since moved away from rendering sarx as “sinful nature.” When translators try to help us too much by interpreting instead of translating, their interpretation can become part of what we think the Bible actually says. When something does not line up, going back to the word in its context helps us see it in light of the gospel. This is where reading a challenging passage from more than one translation can be a good place to start.

I do not believe we have a sinful nature as Christians. Our nature is divine according to Scripture, but that does not mean we always do holy things. We are still prone to sin, and our mind seems to be the source of the issue, not our core being or who we are in Christ. The flesh is not who we are and is not part of our soul or core being. I believe it is more of an external influence we can fall into through our thoughts.

Walking by the Flesh and the Spirit

When we set our minds on the flesh, we begin to adopt an attitude of the flesh. Essentially, we begin to walk by the spirit of the flesh and not the Spirit of our Lord.

That is what we saw in Romans 8:6–8 and Galatians 5:16. When we find ourselves gratifying the desires of the flesh, we know that we have the wrong attitude about something. When we pay careful attention to this, the Lord guides us into all kinds of humbling spiritual growth. Waking up to grace is a lifelong process and, like a child learning to walk, our Father is guiding us along the way.

That is also why learning how the Holy Spirit guides us matters.

Our Old Self Was Crucified With Christ

Romans 6 makes the identity question even clearer.

Paul says that those who were baptized into Christ were baptized into His death, that our old self was crucified with Him, and that one who has died has been set free from sin. He does not tell us to crucify the old self little by little. He says it happened with Christ.

The wages of sin is death. The old person had to die. That is what God accomplished in our union with Christ.

This is why the new creation cannot be reduced to a legal label pasted over the same old person. Something real happened. Our old self was crucified, and our life is now in Christ. That is the same reality behind Paul’s words, “For to me to live is Christ.” (Philippians 1:21)

We still have minds that need renewal. We still live in mortal bodies. We still experience temptation and can choose badly. But we should not interpret those realities as proof that the old person is still our deepest identity.

The better we understand what the Lord has already done, the less reason we have to build Christian growth around self-condemnation. We can face what is wrong without calling the old self alive again. Our identity is in Christ. That is why identity in Christ is more than a position; it is the life from which we now learn to live.

Soul, Death, and Immortality

The word soul becomes especially important when we start talking about death.

A common Christian picture says that the body dies while an immortal soul leaves the body and continues living by its own nature. That picture owes a great deal to Greek philosophical thought. Plato spoke of the soul as immortal and separable from the body, and that way of describing human existence became deeply influential in later Christian tradition.

The historical trail matters because these ideas did not disappear when Greek philosophy met the early institutional church. Writers such as Origen and Augustine taught the soul as continuing after bodily death, and later Protestant theology largely inherited that framework. By the time most of us hear the word soul, the definition can feel biblical before we ever ask how Scripture itself uses the word.

That is why I do not want to begin with Plato and read him back into Moses, the prophets, Jesus, or Paul. The Jewish Encyclopedia and the International Bible Encyclopedia have long acknowledged the tension between the Greek idea of an inherently immortal soul and the way the Old Testament speaks about human life. The question is not whether Christian tradition has used immortal-soul language. It obviously has. The question is whether Scripture requires us to believe every human possesses eternal life by nature.

Scripture gives us a different starting point. In the Old Testament, the Hebrew word nephesh is used for living beings, life, breath, desire, and the person. Adam does not receive an immortal soul as a separate object placed inside him. Genesis describes the man becoming a living being.

Genesis 3:22 is especially important. After Adam sinned, the Lord prevented him from reaching out to the tree of life and eating so that he could “live forever.” Adam was not created with immortality that could never be lost. Everlasting life depended on what God supplied.

That same pattern continues into the New Testament. Romans 6:23 does not contrast eternal happiness with eternal conscious misery. It says, “the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” The contrast is death and life.

Immortality Must Be Put On

1 Corinthians 15:53 says the mortal must “put on immortality.” That only makes sense if immortality is something given, not something every human soul already possesses by nature.

The Lord alone is the source of life. Christ is life. Immortality belongs to what He gives us.

You cannot have eternal torture without eternal life. If the wages of sin is death and eternal life is the gift found in Christ, then we should not quietly give the lost eternal life in order to keep them alive forever for punishment.

I develop that judgment and afterlife question more directly in Gehenna in the Bible and in the study of Lazarus and the rich man. The point here is the foundation beneath those studies: life is in Christ.

Life Is the Gift

The body is mortal. Human life is dependent. Our spirit and inner life are not independent sources of immortality floating free from the Lord.

That brings the whole discussion back together. Spirit, soul, body, and flesh are not abstract theological parts we need to arrange into a diagram. Scripture uses them to show us life as it actually is: created life, dependent life, inner life, bodily life, human thinking apart from God, and the new life given by His Spirit.

We were never meant to produce life from ourselves. Christ is our life, and His life is in us.

And that changes the way we walk. We do not walk by the Spirit by becoming obsessed with what invisible part of us is doing what. We walk by the Spirit as our minds are renewed to the truth, our dependence turns toward the Father, and the life already given to us in Christ begins to show itself.
