The Bible uses the word “flesh” in more than one way, and knowing which sense is meant changes how a passage should be read. Sometimes flesh simply means a human body made of skin and bone. Other times it points to something deeper: a pull toward sin that lives inside every person, working against the Spirit of God. Here’s what scripture actually says about both meanings, and why the difference matters.
What Does “Flesh” Mean in the Bible?
The Hebrew word basar and the Greek word sarx are both translated “flesh” throughout the Old and New Testaments, and both carry a range of meaning depending on context. Sometimes flesh is completely neutral, referring to physical bodies, meat, or humanity in general (Genesis 6:12, Isaiah 40:5). In the New Testament, especially in Paul’s letters, flesh often takes on a second, more specific meaning: the fallen, self-centered part of human nature that resists God and craves sin. Reading “flesh” correctly means asking which sense a passage intends before drawing a conclusion from it.
The Flesh as the Physical Body
The most straightforward use of “flesh” in the Bible is simply physical, bodily existence. John 1:14 uses it this way to describe the incarnation, the moment God the Son took on a real human body: “And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.” This sense of flesh is not sinful or negative on its own. It is simply what it means to be human, made of flesh and blood like everyone else, and it is the very thing Jesus took on in order to live, die, and rise again for humanity’s sake.
The Flesh as the Sinful Nature at War With the Spirit
Paul’s letters use “flesh” a second way, describing an inner pull toward sin that opposes the work of God’s Spirit in a believer’s life. Galatians 5:17 puts it directly: “For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.” Romans 8:5 describes the same conflict as a matter of mindset: “For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.” Paul goes on to list concrete examples of what living according to the flesh looks like, including sexual sin, idolatry, hatred, strife, envy, and drunkenness (Galatians 5:19-21), not as an exhaustive list but as a picture of self-centered living left unchecked. Even the apostle Paul admitted the pull was real in his own life, writing in Romans 7:18 that “in me (that is, in my flesh,) dwelleth no good thing.”
Walking in the Spirit Instead of the Flesh
Scripture doesn’t leave the flesh’s pull unanswered. Galatians 5:22-23 describes the opposite of the flesh’s works as “the fruit of the Spirit,” a very different list: “love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance.” Paul frames the Christian life as an ongoing choice to walk by the Spirit rather than give in to the flesh’s demands (Galatians 5:16), a daily posture of dependence on God rather than a one-time fix. This is the same tension explored in What Are the Fruits of the Spirit? and Common Questions About the Holy Spirit, both of which look at how the Spirit works in a believer’s daily life.
Key Bible Verses
Galatians 5:16-17
“This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.”
Romans 8:5
“For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.”
John 1:14
“And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.”
Frequently Asked Questions
Is “the flesh” the same thing as the physical body?
Sometimes, but not always. The Bible uses “flesh” both ways, so context matters. When Paul warns against living “according to the flesh,” he means the sinful pull inside a person, not the body itself. Having a physical body is not sinful; scripture even describes Jesus taking on flesh (John 1:14) without taking on sin.
Can a Christian ever fully escape the flesh’s pull in this life?
Scripture describes this as an ongoing struggle rather than something resolved once and for all. Even Paul described the fight in his own life (Romans 7:18). The consistent answer across the New Testament is not perfection but daily dependence on the Spirit, one day and one choice at a time.
