I believe I already said that I didn't know much about that, as I haven't really studied that portion of scripture in any detail. So, I'm choosing not to answer, because I don't have an answer for you.
Now how about you answering the question I asked of you? Or are you choosing not to answer?
....a. Did the OT scripture indicate that the sacrifices were efficacious? NO, they didn't. God would say to those who ritualistically engaged in them, "I hate, I despise your feasts." He would say that he didn't require the blood of a bull but that instead he wanted them to "love mercy, do justice, and walk humbly with their God."
2. After the Apostle Paul became a Christian did he ever go to the temple and engage in the worship found in the temple? YES, he did. In fact that's where he was the day he was taken prisoner by the Romans. He had gone there for a purification rite that involved sacrifice. Apparently, as a Jew, Paul had the right to continue in the temple worship. In his mind, he looked BACWARD to the cross of Christ.
3. In the millennial age, are Jewish believers going to SUPPLANT Jesus' eternal REAL sacrifice. NO. They will simply be doing what Paul already exampled. They will be using the sacrifice as a way of LOOKING BACKWARD at what Christ had done.
....a. If the OT never indicated that sacrifices were efficacious, how can one say that THIS OT passage indicates that the sacrifices in the millenial reign are efficacious. It will be the Jewish memorial way of looking BACKWARD at the Sacrifice of Christ.
....b. We use the COMMUNION SERVICE as a memorial to LOOK BACKWARD at the sacrifice of Christ.
