Ro 7:9 For I was alive without the law once: but when the commandment came, sin revived, and I died.
Ro 7:10 And the commandment, which was ordained to life, I found to be unto death.
Ro 7:11 For sin, taking occasion by the commandment, deceived me, and by it slew me.
Ro 7:12 Wherefore the law is holy, and the commandment holy, and just, and good.
Ro 7:13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
It seems to me that Paul has to be talking about someone who has already believed and come to life. They are "without the law." He is relating his trying to understand just what we are speaking of here. Are we under Grace or under the law.
There are fine lines here in trying to work this out in our own understanding. We get an awareness of Grace and then look to our thoughts and actions knowing they are no longer held against us. But at the same time we know that both our thoughts and actions matter.
So where does the law fit in as someone who is saved by Grace.
We do not want to fall back under the law. That is the warning to the Galatians.
My take on it is that we cannot follow the law by our own efforts. And if we try to block out thoughts or words by sheer will they gain power.
For an example, I believe a lot of the problem with Catholic priests and sex is a direct consequence of using force to make themselves stop what they wish to stop. Then the problem gets worse because they are keeping their mind on a problem instead of the solution. The law that they have imposed upon themselves has grown exceeding sinful. We all do the same things in various areas of our lives to various degrees.
We are supposed to believe past the awareness of Grace. The promises that state that we are being changed by the Spirit.
Heb 6:1 Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
Heb 6:2 Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
Heb 6:3 And this will we do, if God permit.
God is changing our hearts so that our desires are changing. It takes time, but once we see that it is happening we begin to get an inkling that even the laws, including the 10 commandments and the circumcision are promises and prophecies.
((Mt 11:13 For all the prophets and the law prophesied until John. Joh 5:46 For had ye believed Moses, ye would have believed me: for he wrote of me.
Joh 5:47 But if ye believe not his writings, how shall ye believe my words?
We are not changing ourselves. We are incapable. He is living up to the promises of the various covenants and promises.))
So, now we can look at the commandments as promises.
Thou shalt not ...is saying in the future you will not covet, lie etc.
Thou shalt ...is saying in the future you will begin to love the Lord thy God with all your heart soul strength and mind.
It does not negate the commandments, it enhances them. God is changing us as He promised he would. The words have not changed, our perspective has.
Just my take on it,
