Now that's an interesting speculation. Taking it a bit further we could surmise that there is no more redemption possible through the blood of Christ (for new sins) because it is finished, Jesus work in that aspect is done, and he will not be nailed a cross again.
Ephesians 3
9 And to make all men see what is the fellowship of
the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
10 To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,
11 According to the eternal purpose which he purposed in Christ Jesus our Lord:
.....
16 That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;
17 That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,
18 May be able to comprehend with all saints what is the
breadth, and length, and depth, and height;
The Messiah, the Christ, Jesus and His ministry was the secret that had been hidden in God.
v11 says that this is
an eternal purpose, forever.
I find the vocabulary interesting in verse 18 the same vocab. used when there is a description of a temple building.
Hebrews 10:29
who hath trodden under foot the Son of God, and hath
counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
If one were to return to sacrificing animals for atonement for sin, as it says in Ezekiel, I believe that is exactly what they would be doing, "trodden under foot the Son of God". All I can say is that if I were alive to see this day, I will not be running off to Israel to participate in this. In Ezekiel it says "all" will do this. So for me this cannot be talking about the millennium or any other time when Jesus is on the earth. If it didn't say "all" then maybe I could see how those who did not receive Him being allowed to do sacrifices on a temporary bases much like the 40 yrs between Jesus death and the temple destruction in 70 AD. But "all". No. Just my opinion of this.
