There is so much to say about how the Apostle Paul has been misunderstood, but let’s start with this one.

Paul was not talking about himself in the last verses of Romans 7:13 “ Did that which is good, then, bring death to me?” This person who is crying out is “speech in character”, a rhetorical method of teaching.* Paul is writing as if he were a person questioning the teaching that Paul is giving.

By no means!( Meganoito, God forbid.) This is Paul answering the question.

“It was sin, producing death in me through what is good, in order that sin might be shown to be sin, and through the commandment might become sinful beyond measure. ¹⁴ For we know that the law is spiritual, but I am of the flesh, sold under sin. ¹⁵ For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate. ¹⁶ Now if I do what I do not want, I agree with the law, that it is good. ¹⁷ So now it is no longer I who do it, but sin that dwells within me. ¹⁸ For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. ¹⁹ For I do not do the good I want, but the evil I do not want is what I keep on doing. ²⁰ Now if I do what I do not want, it is no longer I who do it, but sin that dwells within me.
²¹ So I find it to be a law that when I want to do right, evil lies close at hand. ²² For I delight in the law of God, in my inner being, ²³ but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. ²⁴ Wretched man that I am! Who will deliver me from this body of death? ²⁵ Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin.

Then Paul gives the answer in the first verses of chapter 8—remember that there are no chapter and verse separations in the original letters! 

Note the word “therefore”, the first word in chapter 8.

Chapter 8
​¹ Therefore, there is now no condemnation for those who are in Christ Jesus. ² For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. ³ For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, ⁴ in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit. ⁵ For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. ⁶ For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. ⁷ 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. ⁸ Those who are in the flesh cannot please God. Romans 7:13 – 8:8 Romans 7:13 – 8:8

Paul gave the answer to the question in verse 7:24.  The Spirit of Life in Messiah Yeshua has set us free from the condemnation that comes with disobedience to the law. Without the Spirit of Life we are unable to make choices that lead to life.

c.f. 1 Corinthians 2:9-12

But, as the Tanakh says,
“No eye has seen, no ear has heard
and no one’s heart has imagined
all the things that God has prepared
for those who love him.”
¹⁰ It is to us, however, that God has revealed these things. How? Through the Spirit. For the Spirit probes all things, even the profoundest depths of God. ¹¹ For who knows the inner workings of a person except the person’s own spirit inside him? So too no one knows the inner workings of God except God’s Spirit. ¹² Now we have not received the spirit of the world but the Spirit of God, so that we might understand the things God has so freely given us

Why? Because the Torah of the Spirit, which produces this life in union with Messiah Yeshua, has set me free from the “Torah” of sin and death Romans 8:2
