You are fully missing the New Covenant.
Here where I live...in Canada ...the highways have both a minimum speed (60kph) and a maximum (more of a suggestion really ;) ...100kph) That is to keep traffic flowing.
If those signs could be brought back into the 1700's...people would be talking about the "spirit" of the speed limit signs...as in...keep the traffic moving. It would not be relevant to the actual letter of the signs since those speeds were unheard of at that time. If you told the people of that time that one day there would be horseless carriages that could go well beyond the speed limit of 100kph...you would get unbelief.
That very same kind of unbelief you are now exhibiting.
Fast forward until this present day...and the speed limits make perfect sense. And under the New Covenant the letter of the law makes perfect sense....now fulfilled by those who walk in the resurrection life of Christ.
it isn't God's fault that the law is eternal. AND it shows what eternal life is. What it should show us is that the grace of Christ is there to SHOW the law for what it is. By grace we ESTABLISH law and its purpose.
Unless you engage an actual faith I will stop conversing with you...I pray you come to the faith OF Christ.
This argument is pure sophistry. It implies that grace exists for people to ignore God's laws, and that isn't the least bit true. The purpose of grace is to restore a person to a right standing with God after they repent of violating His commandments. Law and grace function together because neither one of those things would have any purpose by themselves. God's commandments can't restore anybody to being in God's favor after they have violated them, and grace can't keep anyone on the path of righteousness after they are forgiven.
It's amazing how Jude wrote about deceivers infiltrating the Church with these kinds of hyper grace doctrines, and "Christians" today still subscribe to the fallacy that Paul taught people to ignore God's commandments. Paul clearly taught in Romans that the purpose of God's commandments is to give knowledge of what sin is(Rom. 7:7) so people would avoid it and quit committing it, not to point people towards grace.
Having the living faith that Christ had involves keeping His Father's commandments. You clearly don't know the difference between having the faith
of Christ and having faith
in Christ, so it's obvious to any knowledgeable person that you're not anywhere near being the New Covenant expert that you want to think you are. In all of the letters Paul wrote, he didn't once state or imply in
any way that the role of God's commandments was to point people to grace.
The Sabbath is not really exclusively a moral law alone. At the heart, it’s a ritual law or a ceremonial law. Nobody can instinctively obey the Sabbath without God telling them about it. Moral laws are doing good instinctively without a command telling you to do it.
“For when the Gentiles, which have not the law, do by nature the things contained in the law,…” (Romans 2:14).
The Sabbath is not a ceremonial or ritual law. Ceremonial and ritual laws were things like the incense burning, leaf sheaf waving, ritual cleansings, food and animal offerings, etc. There isn't a single NT writer that ever referred to the Sabbath being a ceremonial or ritual law, and you won't find a passage that honestly supports this false theology.
Hebrews gives a very good outline on all the things that were temporary, and the Sabbath clearly wasn't listed among them. No matter how dishonest people twist Paul's words in Hebrews, they can't make their false theology true. The Sabbath was created and codified in stone by the very hand of the Creator, and it was declared by the same Creator as being a permanent obligation for the people who are truly under covenant with Him. That is the truth.
When Paul talks about Gentiles instinctively doing what God's commandments require of them in Rom. 2:14, he was clearly referring to the last 6 commandments. Gentiles have no knowledge of God, and therefore cannot be expected to know anything about the true God or how He expects to be worshiped or loved. They can however, know that their parents should be respected, that they should not commit adultery, lie, murder, steal, or covet things that don't belong to them.
