I am only trying to bring to the front what I believe has been put off, which is the relevance of the Law and the 10 Commandments. Not as the means of salvation but relevant to it in the deepening understanding of the will of GOD for doctrine, reproof, correction, and instruction in righteousness.
The power of sin is the law 1Cor15:56 The legally binding law with the power to condemn. It’s important to remember that when reading romans.
In romans ch3:20-30 Paul explains the believer can have no righteousness before God of obeying the law, they have righteousness apart from law, their righteousness is faith in Christ. Paul maintains believers are justified apart from law. What would some of his readers have thought after reading those verses? ‘Well if we are righteous before God apart from obeying the law we can act however we like and remain saved.’ Paul of course would have known that, hence verse 31:
Do we then make void the law through faith? God forbid: yea, we establish the law. Rom3:31
You have to be able to understand Paul’s message as one cohesive whole.
Paul stated:
Christ is the end of the law UNTO RIGHTEOUSNESS(not full stop) to everyone who believeth Rom10:4
For Paul also wrote:
Wherefore the law is holy, and the commandment holy, and just, and good. Rom7:12
The above is in relation to the moral law, or ten commandments.
So what was God to do? He obviously wouldn’t want to remove what is holy, just and good, but He also wanted to take away what condemned man. The law comes in two parts. What is written in the law, and the attached penalty for transgression. Nothing wrong at all with the first part, it’s the second part that's the problem. So God did an incredible thing, he abolished the law, in the sense of what we all understand law to mean. For he removed its condemnation by sending Christ to die for our sins. But He then transferred what is written in the law from an external law written on tablets of stone to an internal law written on tablets of human hearts(2cor3:3) Paul states in rom ch2 the law(what is written in the law) is in believers hearts(Gentiles hearts was specifically mentioned).
So, by removing a legally binding law that condemns, the power of sin was also removed. But what is holy, just and good remains, it is now in believers hearts, meaning in believers hearts they do not want to murder, commit adultery, steal, bear false witness, covet etc. That law cannot condemn you, for you have a saviour from your sin, the penalty of sin has been removed, but it does stop you having a licence to sin under grace, for in your heart you desire to live as God wants you to live, you want to live according to what has been placed in your heart, what is holy, just and good.
Therefore, with the power of sin removed from your life (the legally binding law with its power to condemn) you can now live far more as you in your heart want to live, for that is where what is holy, just and good now is. And so Paul states:
For sin shall not have dominion over you: for ye are not under the law/righteousness of obeying the law, but under grace/righteousness of faith in Christ. Rom6:14
And so:
Do we then make void the law through faith? God forbid: yea, we establish the law. Rom3:31
Therefore, you can have knowledge of sin through the law, without condemnation by the law, for righteousness of obeying the law has ended.
