Sounds like pro-Jewish Messianic theory. Sorry, but the Jews which Apostle Paul said God had spiritually blinded away from The Gospel of Jesus Christ, are still those Orthodox unbelieving Jew majority living in the nation state of Israel today.
The majority of them there, and in the world, still... reject Jesus of Nazareth as The Christ.
Thus it is not Biblical to push a wishing-well theory about the unbelieving Jews today that still reject Jesus Christ. When God removes their spiritual blindness when Jesus returns, that will be their time to understand and believe, or continue to reject Jesus.
The Daniel 9 seventy weeks prophecy is specifically applied to Jerusalem and Daniel's people, the Jews. So we cannot apply Christ's Salvation to the majority of them, because they still reject Jesus today. Thus it is ignorance to try and apply all those things in Daniel 9 as already having been fulfilled for the Jews today.
You are right to say that Chapter 9, as well as all of the visions were written to the Jews and His city! This is exactly the “big picture” of the Book of Daniel.
The Book of Daniel is all about the restoration of His people and His city AFTER their 70 year punishment and exile in Babylon.
It begins with their captivity. It reveals their life while in Babylon. While there, God gives us the long term prophecy of the 4 kingdoms that He has selected to place His messianic prophecies, and many others, in.
And He will reveal them to us as His people travel through these 4 kingdoms. He will give Daniel the most important prophecy in the Bible! The 70 weeks of years prophecy is a prophecy that DETAILS this “restoration” of His people and His city back to its pre-exile time. Again, this is the “big picture” / purpose of these prophecies.
And within these prophecies, God will reveal His coming and crucifixion, His God given 6 fold mission (9:24), and the setting up of His church.
So, once again, Daniel is written TO and FOR His people and His city - not folks some 2000 years in the future. Certainly, the Book of Daniel is relevant to ALL people of ALL generations, but it was SPECIFICALLY GIVEN TO AND FOR THOSE WHO WERE RETURNING TO JERUSALEM.
In Chapter 2, the Stone would strike the FEET ONLY, and break into pieces the iron and the clay (ONLY) from the feet of pagan Rome. The Clay represents His people that were subjugated and controlled within pagan Rome.
His striking the feet would separate (symbolically) His people into 2 categories: those who would accept Him as their Messiah, He would refer to as “pottery clay.” Those that would continue to reject Him even after the Cross and His resurrection, would be referred to as “ceramic clay,” because their hearts were hardened and they would continue to exist as they did prior to His death. This can be found in verses 2:41-44.
Therefore, the 70 weeks of years prophecy begins in 457 BC for 490 years until 33 / 34 AD when it comes to its end. This period / prophecy covers ALMOST all of Daniel AFTER they leave Babylon. This is because it is all about THEIR RESTORATION BACK TO JERUSALEM.
However, WITHIN these prophecies for the restoration of His people and His city, God will also include the most important messianic prophecies- the coming and death of their Messiah.
Take a good look at verses 9:24-25. These 2 prophecies reveal the complete “restorative” prophecies: they tell us the physical elements of the “restoration” that will be completed. They also tell us who is responsible for their completion (His people). And finally, they also tell us when WITHIN the 70 weeks they will be completed.
You might also notice that within these 2 verses, God also tells us the LAST piece of the restoration process in this prophecy: that would be the restoration of the Ark of the Covenant in the Holy of Holies. This is the only piece of furniture the Jews could not restore. Thus, God would tell us who will restore it (Jesus would be our Ark), it tells us His mission to restore the “spiritual” elements missing from the fall, and He will tell us exactly when He will complete them.
Thus, the 70 weeks prophecy dominates the Book of Daniel in the amount of time it covers within these 12 chapters, it covers the “restoration” of His people and His city, it reveals the coming of the Messiah!
If we were to stop at the end of verse 26 then the restoration of His people, His city and all of mankind would be restored - fully restored!
But unfortunately, His people would reject and crucify their Messiah. And this would require God, who knows all things, to write verses 26 and 27. These are the 2 “destructive” verses WITHIN the 70 weeks of years prophecy. They cannot be assigned or attributed to anyone but our Messiah. They reveal the consequences of His people rejecting and crucifying their Messiah.
Consequently, these 2 verse will include the exact same physical and spiritual elements found in the 2 “restorative” verses of 24 and 25.
They tell us what is being destroyed, when they will be destroyed and how they will be destroyed. Same elements, same way of presentation. These 2 verses mirror the earlier 2 in a destructive manner (a true 4 verse chiastic structure right in front of us).
1) it is “He” not “he” who will be “cut off” (crucified) in the midst (exactly 3.5 of the last week of the prophecy) - Jesus was crucified!
It was “He” who would confirm the New Covenant (Jeremiah 31:31-34) IN / DURING / WITHIN the last 7 years of the prophecy (there is no word “for” in this prophecy. The Messiah was purposefully meant to arrive AFTER the completion of the 69th week - AFTER His people completed their part in the restoration process. Then, the Messiah would arrive to restore the Ark of the Covenant- something only He could do (and also notice that every part of the “restoration” was completed in the exact reverse order they were either taken away or destroyed by the Babylonians. Keep in mind that Jeremiah took the Ark away- first piece of furniture, so it could not be taken by the Babylonians, thus it was the last piece to be restored! It would be restored on the first day if the last week or 7 years.
All of this is messianic and speaks TO AND FOR His people and His city - THAT TIME IN OUR HISTORY.
The Messiah would be crucified,
The city would be destroyed in 70 AD,
His people would be “MADE DESOLATE” to their God as punishment for the next 2000 years! This would / will end ONLY when God deems the “time of the Gentiles” is over. Then, He will remove the blindness from their eyes exactly as He did with Paul on the road to Damascus.
But also keep in mind that IT WAS GOD’S WILL THE JEWS WERE PARTIALLY BLINDED. This was His doing so the Gentiles would come to know the One true God and be saved. The Jews really had no choice because it was God’s decision.
The last week of the prophecy belongs to Jesus. He fulfilled ALL that His Father asked of Him. The Jews fulfilled all that was asked of them RELATIVE TO THE “restoration” process. The 70 weeks of years prophecy was completed!
It was the consequences, both bad and good, that would begin to take place after the cross that continues to this very day. But it all took place at the time of Jesus.
There is no 7 year tribulation period, there is no “literal” anti-Christ, the Covenant was confirmed DURING the last 7 years (Holy Spirit was indeed sent at Pentecost). The Jews have been made “desolate” to their God for over 2000 years.
The 70 weeks of years prophecy is all about Jesus- the last week of the prophecy and what would and has resulted from His being rejected and crucified by His people WITHIN the last week of the “restoration prophecy.”
