No we have two. Paul describes the old nature that we have very well in Romans 7 as he tells of the struggle that he has with it every day.
Romans 7:14-23 14 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.
Paul mentions the flesh (
sarka), or fleshly members (
melos), four times in the cited passage. He also mentions the mind (
nous) once. All told there are five references either to the fleshly body or the mind. Paul begins this didactic passage with a dichotomy between the spiritual and the flesh (v. 14). To play to your argument, Paul does use the word "dwell" or "indwell" (
enoikeo,
oikeo ) twice. So, how do we put this all together and make sense of it? Verse 23 is a key verse to unpacking the preceding eight verses. Paul saw a different law at work in his mind that was fighting against the work of the Spirit. This law was the mind that is tainted (or trained) by sin and is made manifest by our physical deeds. This is what the reference to "members" means.
When we sin our mind records it. Like a hard drive on a computer our mind retains our sins. It plays back both the pain and pleasure of sin. As we desire to serve God out of our new nature, the old man rears his ugly head and tries to block the way. This is not another spiritual nature but a fleshly nature (c.f. Paul's reference to the flesh/members/mind).

]He describes the individuals of the Corinthian church as carnal--carnal Christians in 1Cor.3:1-5. He tells us there are two kinds of works in Gal.5: the works of the flesh and the works of the Spirit. We can give into either: the flesh or the Spirit. Face it! Your works are not always the Fruit of the Spirit, are they?
You've hit the nail on the head when you mentioned the flesh. This makes my point in regards to the Romans 7 passage. The flesh is not a spiritual nature. It does not compete with the resident Holy Spirit of God.

How many times has this verse been quoted on this thread now as a proof text, and yet without knowledge of what the verse means? It is not speaking of your old sin nature that has passed away. It is not speaking of anything like that at all. To find out its meaning you must read the context and get the meaning from the context:
Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more. (2 Corinthians 5:16)
--What is Paul speaking about? He is speaking to a church that has both Jew and Gentile; rich and poor; and wide variety of people. To use a modern day example you may have a banker and a janitor in your church. Perhaps you also may have someone saved who was recently released out of prison. Perhaps the banker would be prone to look down on the other two people, and the former prisoner might think that the banker would never want anything to do with him.
2 Corinthians 5 is an abridged version of 1 Corinthians 15; a polemic on the resurrection. Verse 17 is telling us we are not just physical creatures, we are now spiritual creatures. And not just any spiritual creature; we are children of God (implied, not stated specifically in the text). Indeed, in verse 1 Paul references the resurrection. The resurrection is possible because of what; the flesh or the Spirit? The Spirit! The flesh is dying and already dead. Dying in that this earthly tent is decaying each day. Dead in that we are already dead to sin and alive to God in Christ. If we retained a spiritual old nature then we really could not be alive in Christ.

If you didn't have an old nature you would never have to repent.
This is a stark admission on your part.
Paul said in 1Cor.15:31, "I die daily." Why?
Friend, what is a stark admission; the fact that I wrote that we must repent daily? Notice I did not write that we must ask for forgiveness daily. We are forgiven for all time. Repentance is a constant turning from sin. I sin every day. When I recognize my sin, confess it, and turn from it I am displaying repentance. That repentance is only possible because of the new nature. The reason I have to repent is because of the war that is waged in my mind and sin that is exhibited through my members.
