Most Christians interpret Rom. 7:6 to mean that the Torah has been cast aside and that we don’t have to live by the rules of the Torah anymore. Life does not come from the letter of the Law — and it never did.
We deserve death under God’s holy law, but Yeshuah the Messiah gives us life to live the law with a new “heart.” That’s the message of יום כיפרים Yom Kippurim, the Day of Atonement.
