Jesus’ work is not half done - He said “It is finished!” The term “New Covenant” is used in Isaiah, Ezekiel and, of course, in Hebrews (written just before the end of the Old Covenant age).
I do not reject the Torah - but how can anyone be obedient to it without the blood sacrifice? There is no option to skip that part - no other path to justification before God. What I do accept is the sacrifice of Jesus as the once and for all propitiation for our sins. That can be the only reason not to continue the requirements of animal sacrifice.
The trap, I fear, is in believing that obedience to the law will gain us any reward - unless it is obeyed without flaw. God knew this was not possible, so he provided for the sacrifice on animals for atonement of our sins.
How can you be saved without the atonement for sins? Animal sacrifice was stopped forever in 70 AD. Jesus is the only way. He did not leave another option.

What he said is finished was the work as Cohen Gadol.
It was something he had to say, just as Pilate had to confirm that there was no fault in Yeshua, our Passover lamb.
The phrases are a part of Torah, just like everything Yeshua and his apostles did day in and day out.
Yeshua has plenty left to do.
