The Law brings condemnation to the natural man and therefore he hates it. Those seeking peace with the Creator recognize the Law is a flashlight on their soul. The Law cannot save, that is not its purpose. You may try of your own strength to keep the Law, but will fail. The Law is to drive you to desperation and to cry out for help from the only Source of help in the universe to keep us from eternal damnation. Once a man is born again (and only then) will he see the Law as liberty, mercy and justice. Otherwise man will point at the Tree of knowledge of Good and Evil and say "Why does God punish us so, that we may not eat of it?" But in Truth, Adam looks back with severe regret and wishes he had followed the Law to the letter and saved everyone the mortality of mankind. In that very real sense, the Law is Life.
Hallelujah! Blessed is the Father, who gives us eyes to see!
Paul could not have said it any better!
And that leads us to John, who says we know we love Yahovah when we are walking in His commandments...
So the commandments are a bellwether for you and I - They let us know whether we are following YHWH, or man, or the 'natural man'... I do not try to keep Torah to attain salvation - I keep Torah because I love Yahovah and in order to follow Yeshua...
What then do we do with an institution that says the Sabbath has moved, or that there is a difference between moral law and ceremonial law, or that establishes holy days, rites and rituals not found in Torah? Even when they claim authority to do so?
It is an easy question.
