Every pot in Jerusalem and Judah will be holy to the L-RD Almighty, and all who come to sacrifice will take some of the pots and cook in them . And on that day there will no longer be a Canaanite in the house of the L-RD Almighty. It is irrational to believe that Yeshua came to earth to do away with the sacrifices, just to reinstate them again during the millennium. Only after the millennial reign will sacrifices cease, because it is at this time that heaven and earth pass away. All of the animal sacrifices must still be for today.
Animal sacrifices are unable to remit sins.
If they could, then salvation would be through the Torah. No, atonement is only through the blood of Yeshua. That is why it has always been necessary for Him to be crucified. He is the perfect sacrifice, and as such, does not need to be offered up continually as do the sacrifices. Secondly, they would be for our sanctification, which means they would be for setting us apart unto G-d.
