Let me try to clarify..
I was trying to express:
We earned just penalty of eternal death due to our sin
Yeshua, because He was totally sinless was, by His death, able to pay our penalty for us
If we choose to accept His payment on our behalf we owe to Him our obedience to His Torah/Law/Instruction.
Nothing in G-d's Torah/Law/Instruction had died, been buried, expired, been replaced or been done away with. G-d's Torah/Law/Instruction is eternal, as is the penalty for breaking His Torah/Law/Instruction. THAT is why we need an ongoing relationship with Moshiakh and communication with HaShem! Thanks to the Ruakh we are able to be somewhat better at obeying G-d's Torah/Law/Instruction, but no one can keep it flawlessly. That fact does not excuse us from our responsibility to daily make an earnest effort to get better at it and to confess our failures when they happen.
For those who believe G-d's Torah/Law/Instruction are not incumbent on them the above is by no means meant to be judgmental, just a clarification of the beliefs of my Messianic community.
Also, I am only broaching this topic at all as a mod asked a question
