No one has ever seen a nature. A nature cannot be felt with the hands or painted with an artist’s brush. Like the wind, it is known only by the effect it produces. Consequently, it has always been a difficult concept to define with clarity. Perhaps the most appropriate synonym to use is the word “capacity.” This term emphasizes potential, ability, or possibility for action.

Everything that exists has its own nature or capacity, and everything acts in accordance with its nature. A stone always acts like a stone and a bird like a bird, except in cases of miraculous intervention by God such as the swimming axhead or the water turned into wine (see II Kings 6:1-7; John 2:1-11).

Birth determines the nature of all living things on the earth. Life born from a horse will have the nature of a horse. And life born of man will have the nature of man. A basic difference between the nature of man and the nature of any other creature is that man has a spiritual dimension as part of his nature. He is a spiritual being. His nature finds expression through the normal components of personality-the mind (intellect), the heart (emotions) and the will (power of choice).

At the time of creation, the mind, heart and will of Adam and Eve reflected perfectly the image of God. But when they sinned, there was a change in their nature that was a tremendous “fall” from that which God had created. They became possessors of a sin nature. And they have passed this nature on to all of their descendants.

The Word of God clearly declares that as a result of birth in Adam’s race, the mind, heart and will of every man is characterized by an inability to become holy. He has absolutely no capacity for receiving or performing the things of God; such is not his nature (Isa. 64:6; I Cor. 2:14). His only potential in God’s sight is for sin. Indeed, he is controlled by sin (Rom. 3:10-12). Paul reminds the Ephesians that before they were saved they were “dead in trespasses and sins” and “were by nature the children of wrath” (Eph. 2:1-3).

But just as birth into Adam’s family gives man Adam’s nature-a sin nature-so birth into God’s family gives man God’s nature-a divine nature. Peter states in II Peter 1:4: “Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature.” This divine nature is the goal and result of the new birth: “Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new” (II Cor. 5:17).

In making us a new creation in Christ Jesus, God does not reform or rehabilitate the old Adamic nature. Rather, He introduces into our lives a new capacity of mind, heart and will-an entirely new nature. With this new nature we have the capacity of mind to “know the things that are freely given to us of God” (I Cor. 2:12). We have the capacity of heart to “love him, because he first loved us” (I John 4:19). And we have the capacity of will to “let not sin therefore reign” in our bodies (Rom. 6:12). This nature makes possible a life that is pleasing to the Lord.

Thus far we have observed that every man born into Adam’s race has a sin nature. Furthermore, every man who is born again is given a new, divine nature through the new birth. These truths lead us to a very important conclusion. While the unregenerate man has but one nature, the regenerate man has two natures-the old capacity from Adam and the new capacity from God.

This conclusion has been a point of contention and misunderstanding among believers throughout the course of Church history. Many have argued that the impartation of the new nature automatically eradicates the old. But a correct appraisal of Scripture will readily demonstrate that such is not the case. The fact of the continuing existence of the old capacity along with the new is repeatedly affirmed in many ways.

One example is found in the word “sin,” which is used in more than one way in the Bible. In some places the word refers to the acts of sin in a man’s life, and in others it refers to the source of those acts, the Adamic nature. This distinction is especially notable in Romans 6:1-8:13 and I John 1:1-2:2. A case in point is I John 1:8: “If we say that we have no sin, we deceive ourselves, and the truth is not in us.”
Two factors are important here. It is distinctly the sin nature that is in view, and furthermore, the entire passage is addressed to believers and includes all believers. John is strongly affirming that every born-again person has a sin nature. Anyone who denies this fact is self-deceived and has no truth in him.

Another important word that evidences the fact of the believer’s sin nature is “flesh” (sarx). Its general reference is to the physical body. However, there is also a moral or ethical meaning. An example is Romans 7:18: “I know that in me (that is, in my flesh,) dwelleth no good thing.” The term is used here to signify the totality of a man’s old capacity, which is his as a result of the Fall. The term “flesh” is not synonymous with the term “old nature,” but it does include the old nature. Since the body of flesh is the vehicle through which the old nature operates (Rom. 13:14; 6:12-19), the term “flesh” is used to represent all that that nature is and does.

That we retain the flesh as an active force is seen in 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.” If the flesh was not a continuing force in our lives as believers (the only men who have the Spirit), then why does the Spirit fight?

A third term the Scriptures use to designate our Adamic nature is “the old man.” Reference to this is found in Romans 6:6, Ephesians 4:22-24 and Colossians 3:9,10. It has in view the total unregenerate personality- the old, unrenewed self which we were because of our connection with Adam. The “new man” is our new nature “which after God is created in righteousness and true holiness” (Eph. 4:24).

An examination of these passages which deal with the “old man” has led some Christians to conclude incorrectly that a genuine believer does not have the “old man.” In Romans 6:6 Paul says that “our old man is [was] crucified with him, that the body of sin might be destroyed.” If “destroyed” were the best translation, then we might conclude that after salvation our “old man” is actually gone. But the Greek word katargeo which is used here, has the meaning of “being done away” or “rendered inoperative.” Williams translates it this way: “For we know that our former self was crucified with Him, to make our body that is liable to sin inactive, so that we might not a moment longer continue to be slaves to sin.”

Paul is not saying that we died with Christ in order that the sin nature might no longer be able to operate within us. Rather, we died with Him in order that the sin nature might be deposed as our master. The point is not that the old nature is destroyed, but that our obligation to obey it is ended.

The same idea is found in Ephesians 4:22-24 and Colossians 3:9. Correctly translated, these verses acknowledge that the believer’s “old man” has already been put off. But that is not to say that it cannot possibly act any longer. The exhortation is that, in light of the fact that the right of the “old man” over our lives has been broken, we should start living as though we believed it. The clear implication is that even as believers, we could be allowing the “old man” to reign.

The biblical discussion concerning “sin,” the “flesh” and the “old man” gives abundant evidence to the fact that as Christians we do retain the old nature along with our new divine nature. It should be immediately obvious that where two capacities are focused in opposite directions, there will be conflict. Paul states in Galatians 5:17: “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.” The present tense of the verbs shows this to be a continual conflict. The verb “are contrary” (antikeimai) is especially important. Not only does its present tense indicate continual conflict, but its meaning suggests that the struggle is an intense one. There is no biblical evidence of any believer who ever came to the point of no longer experiencing conflict. Nor is there a hint that any will ever come to that point while in the body.
This fact of continual conflict could lead to real spiritual depression if we fail to view this conflict correctly. As already mentioned, some have evaded the issue by denying that a genuine believer will experience struggle. They declare that either initial salvation or a second blessing destroys the old capacity for sin. It is exactly this error that John warned against in I John 1:8.
Others often make the mistake of trying to suppress the old nature by observing sufficient rules. Such a law-principle is doomed to failure because it depends for strength on the very flesh from which it seeks deliverance.
Still others try to escape the reality of conflict altogether by conceiving of themselves as spectators watching a battle between two inner forces over which they have no control. The popular illustration of the old nature being a black dog and the new nature a white dog perhaps unintentionally promotes this erroneous concept. The danger of this way of thinking is that it tends to relieve the individual believer of any responsibility. If he sins, he can say in an almost detached way that “my old nature won,” as if he himself was not really liable. After all, he didn’t do the fighting-he was just watching the battle.
The correct biblical view of the matter is that as believers we do have two natures. Both natures are alive and seeking to express themselves in our lives. But despair is not inevitable if we accept God’s plan for victory. That plan involves a perfect balance between God’s provision and the believer’s responsibility.

The first step in God’s provision for victory is the condemnation of our sin nature at the cross. Through the death of Christ, God has passed judgment on our sin nature. This is the truth of Romans 6:6, as stated above. The same declaration is made in Romans 8:3: “What the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned [judged] sin in the flesh.”

Again, the glorious truth of these words is that the sin nature no longer has an inalienable right to the control of our lives. That sin nature can still operate and it is still active. Its essential character was not changed in the slightest by this judgment-that was not its purpose. The purpose of the judgment was to change our relationship to the sin nature. God has declared that our former relationship of obligation to it has been severed. We no longer need to submit to its authority, for that right to rulership has been broken.

Since this is the truth God has declared, our responsibility as Christians is to believe Him and to evidence that belief by action. The application stated in Romans 6:11 gives the idea: “Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.” To “reckon” is not to pretend but to take into account, to consider, to recognize as true. We are to recognize that in God’s sight we are in a position of being dead to sin, because of the cross. The fact that “reckon” is a present tense verb demonstrates that this recognition or belief must be a continual habit of practice.
Consequently, God’s judgment of the sin nature has made it possible for us to be delivered from its power. Now the question is, How can this possibility be fulfilled in everyday life? God’s answer is the indwelling Holy Spirit. Paul writes in Romans 8:3,4: “God … condemned [judged] sin in the flesh: that the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.” God’s plan is that His Spirit live His life through us, giving victory in conflict. He proposes both to control the old nature and to manifest the new. Genuine victory must include both.

But the fact of the Spirit’s presence does not automatically assure victory. We have the responsibility to continually yield to His control. This is the thought of Galatians 5:16: “Walk in the Spirit, and ye shall not fulfill the lust of the flesh.” It is the Spirit alone, working through our new nature as we give Him liberty, that can give victory.

An important distinction should be observed in conclusion. Our new nature and the indwelling Holy Spirit are not one and the same. A nature is a capacity; our old nature has the capacity to do evil, while our new nature has the capacity to do good. Neither is the same as its energizing power. To have a radio is not necessarily to have sound. The radio must be energized by some power. The radio is not the same as the power. Similarly, the new nature is not the same as the Holy Spirit. To depend on the new nature apart from the Spirit is to invite certain defeat. The Apostle Paul discovered this truth the hard way. He relates in Romans 7 that he was endeavoring to be victorious in the Christian life by battling the old nature with his new, divine nature. The result was spiritual disaster. But when he came to recognize that he should rely on the Holy Spirit to work through his new nature, he found the key to victory. With us, as with Paul, conflict will still be present. But it will be a conflict waged by the Holy Spirit.

Do not be confused. The battle spoken of in Galatians 5: 1 7 will be present as long as we are in the body. But conflict is not sinful; defeat is. God never demanded that the believer live without conflict, but He does command that he be victorious in it. The full power of the Holy Spirit is available to fight the battle. Through a yielded walk of dependence on Him, victory can be assured.

  1. A man I respected recommended this. Forty-seven (47)
    years later, I continue to thank God for His victories He has given. I recommend reading this as a followup,
    Companion to Romans chapters 6,7,8.

    • Thank-you for sharing, Charles. This “Two Natures” booklet has helped
      many. Yes, we recommend reading Romans 6,7 & 8 and William Newell’s
      commentary on Romans is very helpful in understanding these sanctification
      truths. lkp

      • I have a printed copy, from May, 1969, The Good News Broadcasting Association Inc. I am confident this was the radio program, “Back to the Bible Broadcast” (with Theodore Epp.)…. dispensationalwoman? I hesitate to ask but what is the difference between Dispensational Theology and Reformed Theology? All I know is I that I have been blessed and have grown spiritually from two Bible teachers who did not see “eye to eye” about some things. They are both with our Lord, Miles Stanford and John Gerstner, Sr.

      • There is much information on the subject of Reformed Theology at Middletown Bible Church .org Miles always said take the good & leave the rest. He encouraged to read the BEST. Hebrews 11:6; 2 Tim.2:15…thank you for sharing.

  2. That was exactly what I needed! Yes! exactly. ..a very basic reminder that I needed. I instantly had an increase of peace about a decision, thanks.l
