Paul has already told us back in verse 5 “For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death.”
So we know beyond any doubt that in verses 9-10 he has to be speaking of the man he was before he had met with faith in Christ. That of course means that he was yet fixated with his mind in on the flesh rather than in the spirit of God. In other words, he is speaking of when he was yet a carnal minded man, not yet having been born again.
Romans 7:9 “And I was alive apart from the law once: but when the commandment came, sin revived, and I died;”
Paul was alive until he was able to learn of his sin by hearing God's Law: (For until the law sin was in the world: but sin is not imputed when there is no law.” Romans 5:13
Romans 7: 10 “and the commandment, which [was] unto life, this I found [to be] unto death:
Thus the very commandments which was, or would have been, life to him as a born again spiritual minded man, was made to be death by the sin he practiced while in his carnal state of mind, not yet born again, fixated by a fleshly selfish focus in the way he thought about things.
Romans 7:11 “for sin, finding occasion, through the commandment beguiled me, and through it slew me.”
Thus it was really that sin in the world posing temptation to him, and which he in his carnal state of mind could not resist, that was using that Law to work death to him. Paul told us at Romans 5:12, “through the disobedience of one sin entered the world.” And as a carnal thinking man Paul, like all other men, was weak in his defenses against it's temptations.
So there here in 7:11, before Christ helped him to leave his carnal thinking and be renewed in the spirit of his mind by being born again, he was yet able to be beguiled by the presence of that sin in the world. That sin which constantly tempted him is what made the Law be death to him, for that Law stated: Deuteronomy 27:26 “Cursed <H0779> be <H9999> he that <H0834> confirmeth <H6965> not <H3808> all <H3605> the words of <H1697> this <H2063> law <H8451> to do <H6213> them <H0853>. And <H0559> all <H3605> the people <H5971> shall say <H0559>, Amen <H0543>.”
Deuteronomy 28:15 “But it shall come to pass, if thou wilt not hearken unto the voice of Jehovah thy God, to observe to do all his commandments and his statutes which I command thee this day, that all these curses shall come upon thee, and overtake thee.”
Having established that Paul is very clearly speaking of himself as the man before Christ who was yet stuck in his carnal thinking, we continue on.
Romans 7:
12 So that the law is holy, and the commandment holy, and righteous, and good.
13 Did then that which is good become death unto me? God forbid. But sin, that it might be shown to be sin, by working death to me through that which is good; -- that through the commandment sin might become exceeding sinful.
There in verses 12 and 13 we see that the Law is holy and righteous and good and he wants us to be clear on the point that the Law is not bad, but it is the sin in this world which exists to tempt man which is bad. And he wants us to understand that in God's wisdom he designed that Law so as to expose that sin, that that sin might be seen as exceedingly sinful by us. That is so that we would come to hate sin and be inclined to be willing to prepare in our hearts to fully embrace the promised Messiah when he would come, For it has always been God's plan that it would be through the Messiah that we would find release from that predicament. A huge part of that by being born again to a renewed spiritual mind that can keep God's law from the heart and eventually through practice and the development of sound habits no longer need sacrifice for sins, as we would then be completely free of sin's ability to tempt us. That then we also mean that we would no longer be one of the ones who are responsible for keeping sin present in this world.
Yet speaking as the carnal minded man before Christ, Paul goes onto say:
Romans 7:14 “For we know that the law is spiritual: but I am carnal, sold under sin.”
Notice there that he is under sin due to being carnal minded. Adam sold us all out to sin by his choosing to sin. Thus Adam set up sin as a master over us along with himself. But no man can serve two masters and sin was a more powerful master than was Adam after he had sinned. For in sinning he made himself to be also a slave of sin.
Romans 7:
15 For that which I do I know not: for not what I would, that do I practise; but what I hate, that I do.
16 But if what I would not, that I do, I consent unto the law that it is good.
17 So now it is no more I that do it, but sin which dwelleth in me.
There is no doubt that Paul is yet speaking as the carnal minded man before Christ. And we have seen clear evidence from Paul's own words that the sin he fell prey to was in the world around him. So why does he now say that sin was in him as a carnal minded man? Because that is what sin does. It plays with our mind and heart and emotions, thus making it appropriate to speak of it as though in us once we have fallen prey to it's influence in the world around us.
Romans 7:18 “For I know that in me, that is, in my flesh, dwelleth no good thing: for to will is present with me, but to do that which is good [is] not.”
Matthew 5:6 “Blessed are they that hunger and thirst after righteousness: for they shall be filled.”
Luke 4:28 “And they were all filled with wrath in the synagogue, as they heard these things..”
If our mind is carnal nothing much good can fill us. We may yet desire to do good but the ability is not present with us. We may even delight in the Law of God while yet being only Carnal in our thinking. We see that every day among those whose zeal is for that Old Law yet they have rejected Christ. They delight in the Law in their inward man, but having rejected Christ and so remaining carnal in their thinking, they are rendered unable to really benefit from that delight. Paul told us that in a couple of different places: Romans 10:2-3 “For I bear them witness that they have a zeal for God, but not according to knowledge. For being ignorant of God's righteousness, and seeking to establish their own, they did not subject themselves to the righteousness of God.”
Paul tells us about himself: “though I was before a blasphemer, and a persecutor, and injurious: howbeit I obtained mercy, because I did it ignorantly in unbelief..” 1 Timothy 1:13
And yet Paul also tells us about himself: “and I advanced in the Jews' religion beyond many of mine own age among my countrymen, being more exceedingly zealous for the traditions of my fathers.” Galatians 1:14
So we see that it is a huge mistake to think Paul is not yet speaking of the carnal minded man before Christ as you read on in Romans 7:19-24.
But in verse 24 Paul speaks clearly of only the future hope of being delivered from that death by means of Jesus Christ and not that he has come to Christ as yet. So he is speaking of the hope a carnal minded man can look forward to:
24 “Wretched man that I am! who shall deliver me out of the body of this death?”
How then do we correctly understand verse 25?
25 “I thank God through Jesus Christ our Lord. So then I of myself with the mind, indeed, serve the law of God; but with the [carnal mind of] flesh the law of sin.”
In verse 25 Paul has begun speaking as he did back in verses 5 and 6, set free from the carnal mind. Review verses 5 and 6. And in the second half of verse 25 Paul shows keen awareness of never returning to that carnal mind.
That completes Romans 7.
