In this article, I will do my best to properly define some Bible terms that sometimes may confuse us. Have you ever noticed that we Christians, everyone in fact, often use words and concepts regarding which we have very little real understanding? We assume we know, but when pressed, we realize that we do not. In the church, we sometimes refer to the “danger” of speaking in “Christianese,” using terms with which we may be familiar, but have little or no meaning to those outside the church. Sadly, we may assume everyone who is listening to us understands our meaning, but often it is questionable if we do ourselves! This is especially true regarding the  words and phrases that I will cover in this article. I hope you will take the time to think through each of these terms. Growing in understanding will enlarge our appreciation of the gospel.

The “old man” – (Greek: palios anthropos)

When God created Adam, he formed his body out of the dirt and breathed life into his spirit.

Then the LORD God formed man (his body) of dust from the ground, and breathed into his nostrils the breath (Hebrew: breath, wind, spirit) of life; and man became a living being (literally: soul). Genesis 2:7 (NASB) 

Adam became a living soul or being. I and many others define the soul as being the mind, will, and emotions – what we call the personality. Greek and Hebrew use three distinct words for spirit, soul, and body. In both languages, the word for spirit also means breath or wind. Paul acknowledges this three-part construction of humans in 1 Thessalonians 5:23.

Now may the God of peace Himself sanctify you entirely; and may your spirit and soul and body be preserved complete, without blame at the coming of our Lord Jesus Christ. 1 Thessalonians 5:23 (NASB) 

God created us in his image. He is a Trinity (Father, Son, and Holy Spirit), and so are we (spirit, soul, and body). Understanding how God’s great salvation affects each part is necessary to have an excellent understanding.

I have written in more detail about spirit, soul, and body in the linked three articles.

Before the Fall, Adam’s spirit, body, and the resultant soul were in complete harmony. Neither sin nor death had entered the world; nevertheless, Adam’s state of moral innocence was no match for the sinful allure of attempting to be independent from God and the manipulative accusation and deception of the enemy.

But I fear, lest somehow, as the serpent deceived Eve by his craftiness, so your minds may be corrupted from the simplicity that is in Christ. 2 Corinthians 11:3 (NKJV)

When Adam believed the lie and chose to disobey God’s clear command, his spirit became alienated from God, which is a form of death. Spiritually he died that very day; although, it did not take out his body for many years.

but from the tree of the knowledge of good and evil you shall not eat, for in the day that you eat from it you will surely die." Genesis 2:17 (NASB) 

This condition of spiritual death has been passed on to succeeding generations from Adam.

remember that you were at that time separate from Christ, excluded from the commonwealth of Israel, and strangers to the covenants of promise, having no hope and without God in the world. Ephesians 2:12 (NASB) 

Death permeated humanity spiritually, physically, and in the personality, or soul. In addition, the entire universe entered into a kind of death spiral, which Paul called “slavery to corruption.” (Romans 8:20-21)

This post-fall-of-man combination of a spirit alienated from God and a body programmed to die resulted in a new version of the soul that was in harmony with sin and deception and fully committed to forsake God and to live a self-directed life, instead of being in submission to and in partnership with God.

This fallen spirit-soul-body configuration I call the “old man.”

The “old man” we all inherit at conception is naturally inclined toward evil. The essential element of the “old man” is the alienated spirit. It is the driving force or generator behind sin.

People who have never been born again (the regeneration of the spirit) can only experience human life through the “old man.”

The “old man” is incapable of being reformed or rehabilitated, because the core problem is an alienated spirit. It has to be put to death and replaced with what the Bible calls  the “new man.” This is precisely what God did through Christ on the cross over 2000 years ago.

We know that our old man was crucified with him so that the body of sin would no longer dominate us, so that we would no longer be enslaved to sin. Romans 6:6 (NET1) 

The “new man” – (Greek: kainos anthropos)

When a person is born again, God regenerates the spirit, the innermost part of our being, which previously had been alienated from God and spiritually dead.

"That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. John 3:6 (NASB)

He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit, Titus 3:5 (NASB) 

This supernatural rebirth causes people to become new creatures spiritually.

The driving force of the “old man,” the alienated spirit, is replaced with a regenerated, reborn spirit which is in complete harmony with God.

Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come. 2 Corinthians 5:17 (NASB) 

and to put on the new man who has been created in God’s image — in righteousness and holiness that comes from truth. Ephesians 4:24 (NET1) 

God’s Spirit becomes one with our spirit, fusing God’s life to ours in the innermost part of our being.

The “new spirit” or “new heart,” which was promised by the prophets, is the result of a supernatural union of the human and the divine in the spirit.

But the one who joins himself to the Lord is one spirit with Him. 1 Corinthians 6:17 (NASB)

"I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me. Galatians 2:20 (NASB) 

"Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. 27 "I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances. Ezekiel 36:26-27 (NASB) 

If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness. Romans 8:10 (NASB) 

The “new man,” as I understand the scriptures, is the combination of the recreated spirit (“inner man” – Greek: eso anthropos), which resides in every believer, with the pre-resurrection Adamic body (“members of my body”), which is still largely influenced by the fall of man.

The regenerated spirit’s desires are in complete harmony with God’s will, but the residual pull of sin, called the “flesh,” remains associated with the pre-resurrected body.

I find then the principle that evil is present in me, the one who wants to do good. 22  For I joyfully concur with the law of God in the inner man, 23  but I see a different law in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin which is in my members. Romans 7:21-23 (NASB) 

The “inner man” or recreated spirit is the source of the believer’s new identity in Christ.

Eventually, at his Second Coming, Jesus will raise our Adamic bodies from the dead, completing our salvation; but for now we only have the “down payment” of the new birth and our union with the indwelling Spirit, which serves as “earnest money” guaranteeing that God will eventually fulfill his promise to fully redeem us – spirit, soul, and body.

In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of promise, 14  who is given as a pledge of our inheritance, with a view to the redemption of God's own possession, to the praise of His glory. Ephesians 1:13-14 (NASB)  

The soul in this “in between time” – the period between the new birth and the resurrection – is being transformed or sanctified (made holy or set apart to God) by the Spirit of grace on a daily basis as we choose to believe the truth (the renewing of the mind) and “walk in the Spirit” – live in dependence, harmony, and obedience to God’s Spirit who indwells us.

But you did not learn about Christ like this, 21  if indeed you heard about him and were taught in him, just as the truth is in Jesus. 22  You were taught with reference to your former way of life to lay aside the old man who is being corrupted in accordance with deceitful desires, 23  to be renewed in the spirit of your mind, 24  and to put on the new man who has been created in God’s image — in righteousness and holiness that comes from truth. Ephesians 4:20-24 (NET1)  

The challenge for us followers of Christ is to identify with Christ’s Spirit, who indwells and is in union with the “inner man,” and realize that the Holy Spirit empowers us to  live above the downward pull of the Adamic body of death, which is called the “flesh.”

 The “flesh” (Greek: sarx)

The flesh is the sinful pull still present in the born again person’s soul, which is connected to the old Adamic order through the body, which has not yet been fully redeemed through the resurrection.

Until then, we are “saved in hope,” which means we are still waiting confidently for the last installment of our great salvation.

For we know that the whole creation groans and suffers the pains of childbirth together until now. 23  And not only this, but also we ourselves, having the first fruits of the Spirit, even we ourselves groan within ourselves, waiting eagerly for our adoption as sons, the redemption of our body. 24  For in hope we have been saved, but hope that is seen is not hope; for who hopes for what he already sees? 25  But if we hope for what we do not see, with perseverance we wait eagerly for it. Romans 8:22-25 (NASB) 

As I wrote before, a born again person is the combination of a new justified spirit (the “inner man”) and a body, which is still linked to the old order of the first Adam.

Until the resurrection, when our bodies are renewed and fully redeemed, believers experience a bipolarity in our souls, a warfare between flesh and spirit.

But I say, walk by the Spirit, and you will not carry out the desire of the flesh. 17  For the flesh sets its desire against the Spirit, and the Spirit against the flesh; for these are in opposition to one another, so that you may not do the things that you please. Galatians 5:16-17 (NASB) 

For we know that the Law is spiritual, but I am of flesh, sold into bondage to sin. 15  For what I am doing, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate. 16  But if I do the very thing I do not want to do, I agree with the Law, confessing that the Law is good. 17  So now, no longer am I the one doing it, but sin which dwells in me. 18  For I know that nothing good dwells in me, that is, in my flesh; for the willing is present in me, but the doing of the good is not. 19  For the good that I want, I do not do, but I practice the very evil that I do not want. 20  But if I am doing the very thing I do not want, I am no longer the one doing it, but sin which dwells in me. 21  I find then the principle that evil is present in me, the one who wants to do good. 22  For I joyfully concur with the law of God in the inner man, 23  but I see a different law in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin which is in my members. Romans 7:14-23 (NASB)  

Being “saved in hope” means we are completely and firmly confident (Greek: hope – elpis) that God will fulfill his promise to raise us from the dead, which will lift us out of our current conflicted state and make us whole again by transforming the Adamic body into something radically new and unaffected by sin and death.

in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we will be changed. 53  For this perishable must put on the imperishable, and this mortal must put on immortality. 54  But when this perishable will have put on the imperishable, and this mortal will have put on immortality, then will come about the saying that is written, "DEATH IS SWALLOWED UP in victory. 55 "O DEATH, WHERE IS YOUR VICTORY? O DEATH, WHERE IS YOUR STING?" 56  The sting of death is sin, and the power of sin is the law; 57  but thanks be to God, who gives us the victory through our Lord Jesus Christ.1 Corinthians 15:52-57 (NASB) 

After the resurrection, we will no longer have a struggle between that which is connected to Adam (the “flesh”) and that which is reborn by God, since there once again will be complete harmony between spirit and body, but this time oriented fully toward God.

In the present however, the “flesh” is the source of spiritual weakness.

I am speaking in human terms because of the weakness of your flesh. For just as you presented your members as slaves to impurity and to lawlessness, resulting in further lawlessness, so now present your members as slaves to righteousness, resulting in sanctification. Romans 6:19 (NASB) 

Even though all believers have “flesh,” we are not ruled by it so that we must live “in the flesh,” which means under the domination of sin.

For while we were in the flesh, the sinful passions, which were aroused by the Law, were at work in the members of our body to bear fruit for death. Romans 7:5 (NASB) 

Walking in the Spirit means we set our minds on God’s truth – the things of the Spirit. When we do this, the power of God enables us to walk in freedom from the downward pull of sin.

Therefore there is now no condemnation for those who are in Christ Jesus. 2  For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and of death. 3  For what the Law could not do, weak as it was through the flesh, God did: sending His own Son in the likeness of sinful flesh and as an offering for sin, He condemned sin in the flesh, 4  so that the requirement of the Law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit. 5  For those who are according to the flesh set their minds on the things of the flesh, but those who are according to the Spirit, the things of the Spirit. 6  For the mind set on the flesh is death, but the mind set on the Spirit is life and peace, 7  because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so, 8  and those who are in the flesh cannot please God. Romans 8:1-8 (NASB)

Walking in the Spirit is called “putting on Christ,” an act of faith by which we choose to identify with the regenerated “inner man” and rely on the indwelling life of God’s Spirit to give us victory over sin.

But put on the Lord Jesus Christ, and make no provision for the flesh in regard to its lusts. Romans 13:14 (NASB) 

Even though, the old man (See above.)  has already been crucified with Christ, the flesh must be crucified or put to death by us on a daily basis. This is equivalent to what Jesus called denying ourselves.

Now those who belong to Christ Jesus have crucified the flesh with its passions and desires. 25  If we live by the Spirit, let us also walk by the Spirit. Galatians 5:24-25 (NASB)

To conclude, our great salvation has past, present, and future components. Jesus accomplished our justification, making us perfectly right with God, when he died and rose again. This was a once for all past event. In the future, we confidently expect God to raise us from the dead, fulfilling his promise and completing our salvation. In the present, we are engaged in an ongoing process called sanctification or transformation, in which we cooperate with the Holy Spirit through belief of the truth and surrendered obedience.

God is changing us day by day into Christ’s image in how we think, speak, and act. Living in the present requires us to draw upon the eternal truth of justification and lock into the hope of the resurrection. It requires us to walk by faith in Christ’s finished work while dealing with the unfinished business of still living in a pre-resurrection Adamic body. It leaves us in a “conflicted” state that necessitates us to keep our eyes firmly upon Christ and his promises.

The “body of sin” – (Greek: soma tes hamartias)

We know that our old man was crucified with him so that the body of sin would no longer dominate us, so that we would no longer be enslaved to sin. Romans 6:6 (NET1) 

This term is more or less synonymous with “flesh.” The body is not evil, but before the resurrection it is linked to Adam’s fall and is an instrument through which we sin.

We can say that the “flesh” is derived from the “body of sin,” since it will only be present as long as these fleshly bodies are still alive. Once the body dies and is resurrected, it will no longer be a “body of sin,” and the “flesh” will disappear.

The “body of sin” participated in Christ’s crucifixion in the sense that we were spiritually identified with (or “in”) Christ when he died and rose again. Obviously our human bodies were not crucified, only the spiritual component. What this accomplished was the nullification of sin’s power or right to enslave us.

We can still choose to sin, but those who died with Christ now have the authority and power to walk in the Spirit rather than in the flesh.

The “body of sin” or the related “flesh” was not annihilated at the cross. It was rendered ineffective in its power to rule us. We can let it dominate us, but we do not have to submit to it. In fact, now it is against our inmost being, nature, and identity in Christ to do so.

Therefore do not let sin reign in your mortal body (Greek: thneto somati) that you obey its lusts, 13  and do not go on presenting the members of your body to sin as instruments of unrighteousness; but present yourselves to God as those alive from the dead, and your members as instruments of righteousness to God. 14  For sin shall not be master over you, for you are not under law but under grace. Romans 6:12-14 (NASB)  

The “body of death” – (Greek: somatos tou thanatou)

This term is synonymous with “body of sin,” but emphasizes the pre-resurrected body’s connection with death through Adam’s sin.

Wretched man that I am! Who will set me free from the body of this death? 25  Thanks be to God through Jesus Christ our Lord! So then, on the one hand I myself with my mind am serving the law of God, but on the other, with my flesh the law of sin. Romans 7:24-25 (NASB)

The “body of flesh” – (Greek: somatos tes sarkos)

and in Him you were also circumcised with a circumcision made without hands, in the removal of the body of the flesh by the circumcision of Christ; 12  having been buried with Him in baptism, in which you were also raised up with Him through faith in the working of God, who raised Him from the dead. Colossians 2:11-12 (NASB)

This term is synonymous with “body of sin” and “body of death.”

Therefore if you have been raised up with Christ, keep seeking the things above, where Christ is, seated at the right hand of God. 2  Set your mind on the things above, not on the things that are on earth. 3  For you have died and your life is hidden with Christ in God. 4  When Christ, who is our life, is revealed, then you also will be revealed with Him in glory. 5  Therefore consider the members of your earthly body as dead to immorality, impurity, passion, evil desire, and greed, which amounts to idolatry. 6  For it is because of these things that the wrath of God will come upon the sons of disobedience, 7  and in them you also once walked, when you were living in them. 8  But now you also, put them all aside: anger, wrath, malice, slander, and abusive speech from your mouth. 9  Do not lie to one another, since you laid aside the old self with its evil practices, 10  and have put on the new self who is being renewed to a true knowledge according to the image of the One who created him— 11  a renewal in which there is no distinction between Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave and freeman, but Christ is all, and in all. Colossians 3:1-11 (NASB)  

By faith we understand that the power of the flesh, the sinful tug of the pre-resurrected Adamic body, has been stripped of its power to rule us. As long as we “walk in the Spirit” by faith in Christ’s finished work and in cooperation with the Spirit’s ever present power indwelling us, we are able to live above the downward pull of sin. This is a daily, even moment by moment, interaction with God’s grace.

Conclusion

My purpose in this article is to provide clarity to some potentially confusing terms. Some may disagree with my definitions, which are an attempt to better understand a mystery. Perhaps God has given you a better understanding than I have. In that case, I hope you will share your insights with me. The important thing is for us to believe what the Bible teaches. We never want to nullify the Word of God just because it has not yet been our experience or is difficult to comprehend. To the degree that what I have written helps our faith, I will consider that I have been helpful. Now we can move on to applying these marvelous truths.
