In Romans 6 we died were raised to new life in Jesus opposed to life in Adam (the old man). In Romans 7 Paul reverses the issues and the law died. The husband represents the law. Paul come to the conclusion that Now we are delivered from the law just as his analogy states. Paul also says it is foolish to return to the law in Gal 3. The law has absolutely nothing to do with salvation before or after the new birth and redemption.
The point of Romans 6 is that was a set free from our old master, our sin nature, to become slaves of our new master, though obedience to the law, which leads to righteousness and sanctification. Sanctification does not come about through disobedience to God's commands, but rather it is His Spirit that enables of to keep them and to transform us to be more like Christ in his obedience to God.
If the husband is the law, then it doesn't work, because we're the ones who died, not the husband. But that's beside the point because Paul states as he is speaking to those Jews and Gentiles who understand the law, so he's using an example from it. It's only no wonder that those who don't understand the law fail to grasp his point. The wife was not delivered from the marriage law by the death of her husband, but from the penalty it would require if she lived with another man while he was still alive.
The Galatians were already saved by faith, but they had begun listening to people who were saying that they had to become Jews and obey the law and oral law in order to be saved. The law was never intended to be kept legalistically in that manner, so Paul was warning them against a perversion of the law, not the law itself.
We are not part if Israel in any shape or form. There is no Jew or Gentile in Christ Jesus. Gal 3:28 and Col 2. If you like my friend bugkiller can prove Israelism is a false teaching. The Christians is not part of the commonwealth of Israel. We share in its provision (Jesus the Messiah).
Ephesians 2:12 remember that you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world.
Ephesians 2:19 So then you are no longer strangers and aliens,[d] but you are fellow citizens with the saints and members of the household of God,
You're in direct disagreement with Paul here. Believers are all God's people and as God's people, we should all do as He instructs.
You argue falsely against the Scripture. In Rom 6 it plainly states not under the law in 14 and 15. The law has no jurisdiction.
If someone is driving down a road with a speed limit of 70 mph, but his wife doesn't like him driving too fast, so he sets his cruise control to 60 mph, then he is not under that law. By exceeding the minimum requirements of the law out of love for his wife, he is driving as though though there is no speed limit. The penalties of the law are not for the righteous, but for the unrighteous.
Similarly, if someone offered to pay for every park fine you ever got, you would no longer be under that law. The law would still be there and you could still break it, but you couldn't be condemned by it. However, that doesn't mean that you should feel free to break that law as much as you want, it would still be good to obey it.
The point Paul is making is in regard to the penalty of the law and in Romans 8:1 that therefore there is now no condemnation for those who are in Messiah, not that there are no instructions for how to practice righteousness for those who are in Messiah. According to Ephesians 2:10 and 1 John 3:10, those who are in Messiah are those who practice righteousness. We know how to practice righteousness and do good works because God has given us instructions in His Torah for our to do that.
If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.
Jesus is not teaching or telling other to keep the law.
Jesus was the one who gave the Torah, so all of it is included in his commandments and is exactly what Jesus was telling them to obey.
You can not earn salvation. It is a free gift without obligation. Self righteousness will only earn you a warm retirement. The wages of sin is death. There are no wages of eternal life. That is a free gift and can not be earned.
He never said anything about earning salvation. That's not why God gave the law to Moses in the first place.
