The only way to make the above work is by refusing to "cast out" the Sinai Covenant of "bondage" in Galatians 4:24-31.
Which is the now "obsolete" Old Covenant in Hebrews 8:13.
Which is the "ministry of death written on stone" in 2 Corinthians 3:6-8.
Which comes from "the mountain that burns with fire" in Hebrews 12:18-24.
If you ignore those passages, maybe you can make your doctrine work.
Therefore, what you are promoting is a doctrine of ignorance.

Briefly mentioned previously
Galatians 4:24-31
So why is Jerusalem and her children compared to Hagar and her children?
Jerusalem as a whole were attempting [Like Abraham Did] to receive the promise through human effort - Hagar, and ended up with Ishmael, a wild man and a pain ever since.
This he did thinking that was how YHWH would fulfill the promise that he would have a son
That's Jerusalem below - Trying to bring about the promise of Eternal life by your own works, and not the Righteousness that comes from YESHUA - YHWH Tsidkenu. Romans 9:32
Jerusalem Above is Free, Free to Obey, As YESHUA gives us all the righteousness we need, puts His Spirit In Us, and writes His Torah upon our heart and mind
But mostly, Blessed is the Man to whom Elohim does not impute iniquity
The Son of the Free women, Sarah when she was well past child bareing years.
Had Isaac
Now Compare - Hagar - Human Effort for salvation
Sarah
Jerusalem Above - He brings it about by tha New Creation, Writing His Torah upon the hearts and minds of His People - Through the working of the Ruach haKodesh, most are stunted, still stuck on elementary things
Obsolete - passing away - Yes - The sacrificial system of the priesthood was obsolete, passing away, and it did in 70 AD
But not forever
Just as Paul warned that Elohim can restore the natural branches, which He will
Since the wild branches are twice as stiff-necked as their fathers.
Ministry of death - Same thing - human Effort
The Law is the Law
The Word for keep in Hebrew is Shamar
It means to guard, protect, put a hedge around
Whoever Keeps and Teaches the commandments will be called the Greatest in the kingdom, whoever nullifies the least commandment will be the least. Matthew 5:19 and not be a priest Hosea 4:6 being that they have forsaken the Torah of their Elohim.
