WPM, I missed your post. But you seem to have also missed mine where I answered you. Don't you remember? I told you, and you rejected, that the temple sacrifices (among other religious practices) mark the people of God as Holy People. Your explanation was way off the mark. God did not prescribe the sacrifices to serve as a temporary covering. This is not a Biblical concept.
Speaking to those who came out of Egypt Moses says,
Deuteronomy 7:6
For you are a holy people to the Lord your God; the Lord your God has chosen you to be a people for His own possession out of all the peoples who are on the face of the earth.
Forget about your definition of Holy, because it's all wrong. The word "holy" isn't a synonym of "moral", or "righteous". "Holy" means "consecrated" or "set apart." Suppose a Jew has two bowls, both of the bowls are exactly alike in every way. He uses the first bowl to eat Cheerios; he uses the second to perform sacred rites in the temple. The first bowl is "common"; the second bowl is "holy". No physical difference between the bowls exist. The only distinction between them is an abstract concept known as "holiness", which indicates that one person or thing has been dedicated to serve God.
God brought the people out of Egypt to serve him. He chose them from among all the other peoples of the earth to be his people. These people are like everyone else. They weren't chosen because they were special or different. They became "holy" when God consecrated them for service.
Deuteronomy 14:2
For you are a holy people to the Lord your God, and the Lord has chosen you to be a people for His own possession out of all the peoples who are on the face of the earth.
What marks or identifies them as his holy people? The marker that identifies them as his holy people is keeping his commandments.
Deuteronomy 28:9
The Lord will establish you as a holy people to Himself, as He swore to you, if you keep the commandments of the Lord your God and walk in His ways.
They did not keep his commandments and they suffered the curses. When the curses are completed, they will return to the land, and once again God will call him "my people." And when they return, they will finally keep his commandments.
Deuteronomy 30:6-8
“Moreover the Lord your God will circumcise your heart and the heart of your descendants, to love the Lord your God with all your heart and with all your soul, so that you may live. The Lord your God will inflict all these curses on your enemies and on those who hate you, who persecuted you. And you shall again obey the Lord, and observe all His commandments which I command you today.
The sacrifices were not temporary coverings for sin. They were markers of a holy people. Keeping the commandments, all of the commandments identifies them as his holy people. We could multiply scriptures, which all make the same point. But the entire story from start to finish is told in the book of Deuteronomy.
ALL of the laws, commandments and ordinances will be performed in the Millennial kingdom because, once again, it serves God's plan to vindicate his holy name.
We have yet to explore what that means.
