You explain how the 70th week is yet to come when Jesus Christ was crucified during the 70th week!
Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times. And after threescore and two weeks shall Messiah be cut off,
That's a good question.
Daniel 9:24-27
King James Version (KJV)
24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
We see Seventy Weeks, or sevens, prescribed for Daniel's People and the City, presumably Israel, an it is at the end of these Seventy periods of Sevens that we see the fulfillment "to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy."
25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.
Scholars debate the time of the decree, but most generally agree that in view are distinct periods of Sevens that represent 49 years, and 434 years. We can answer the question without getting into the details of the decree, but I will just throw in that the next verse tells us, I think, the date we can trace back from.
Notice that from the decree (commandment) to restore and build Jerusalem unto Messiah the Prince (Christ) there is said to be a period of 69 Sevens, which many interpret as a total of 483 years. So if we stop right there, we see that after 483 years the likely event to happen is Messiah arriving.
26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
This is where more debate comes in. Here we see that after the two periods of sevens which are presumably consecutive, at the end, not during, Messiah is cut off, but not for Himself. While that may have confounded the Old Testament Scholar and Student, we can, in retrospect, see this as a likely reference to the Crucifixion of Christ, Who is cut off (killed) at the end of the 483 years, yet leaving a final Week left to be fulfilled.
Some take a view that the "People of the prince to come" is a reference to Christ," an even make some good points which cannot be seen as unreasonable, for the most part. However, we ask ourselves if the People of Christ are going to destroy the City (Jerusalem) and the sanctuary (reference to the Temple), and that seems a little unlikely primarily because we do not have any correlating Prophecy to substantiate the view, plus, we see explicit Prophecy that show that Antichrist will in fact wage an unholy tantrum on Jerusalem and it will be trodden underfoot of the Gentiles, which in no way can be thought to represent Christians.
We also look at our next verse...
27
And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
...which has a few items of interest in determining whether the prince of the people to come is Christ or the Antichrist.
First, this prince will establish the Covenant with many for One Week. In our immediate text we know this represents a period of Seven, which fits with the fact that it is not seen before this, and of course we have a Week left in order for Prophecy to be fulfilled as it always is, to the jot and tittle, according to Christ.
Secondly, we consider what Covenant would be relevant to Daniel's People, Israel, and only two Covenants seem to be suitable candidates, the Covenant of Law, and the New Covenant. Again, some great presentation have been produced to show that the New Covenant is in view, but seeing that The New Covenant is never indicated to be confirmed for a period of Seven Years, and that the Covenant of Law is definitely the First Covenant (pun intended) that would likely be relevant to Daniel's People (an their captivity a result of their failure to observe it, which correlates the fact that these Seventy Sevens are prescribed for Israel), makes it likely that indeed the Covenant of Law is in view.
Third, we see the period the prince of the people that shall come confirms, or strengthens, supports, makes strong the Covenant, and that is the remaining time period not yet fulfilled. So still we see a consistent scenario which we can see correlates to Revelation.
Fourth, we see the same one, the prince of the people to come, who confirms the Covenant for one week...causes sacrifice and oblation to cease, which while some might correlate to Christ abolishing the Covenant of Law, and He did, it is not a consistent scenario we cannot find fault with, because again, Christ did not strengthen either the Covenant of Law or the New Covenant for a Seven Year period, He did not cause sacrifice and the oblation to cease within the time of His ministry, we wouldn't have sacrifice and the oblation under the New Covenant to begin with, and besides all that...
...we already know Christ is cut off after the 69 Weeks.
Not in the midst, or middle of that Seventieth Week.
And I am out of time, so sorry this is kind of incomplete, but to answer the question...
You explain how the 70th week is yet to come when Jesus Christ was crucified during the 70th week!
...the simplest reason is because we cannot place Christ in the Seventieth Week to begin with.
Again, I have seen some reasonable presentations that, if I did not calculate the Prophecy we received in Revelation and 2 Thessalonians 2, as well as more found in Daniel, I might think seeing "the prince of the people that shall come" as Christ as well, except we see He is cut off presumably when the 69 weeks end.
I do see Christ as He that covenanted with Israel, but again, we just can't build a plausible timeline in that view. And only when we get into the New Testament Prophecies do we see a timeline that harmonizes on all point with Prophecy.
The Two Witnesses Minister for 3 1/2 years, are killed by Antichrist (the Beast), who himself is empowered for 3 1/2 years, bringing us not only a total of that last Seven that is missing, but corresponds to the prince that shall come whose people will destroy the City and the Sanctuary seen in Revelation 11. And that is precisely what Daniel 27 gives us. Someone who begins a period of seven years who is supportive of the Covenant of Law (Satan loves to bring people under the Law again) but who by three and a half years has gone by is at a point where he not only causes sacrifice and the oblation to cease, as Paul states, stands in the Temple of God proclaiming himself to be a god. Thus the last half begins with not the Covenant of Law, but Antichrist completely set to destroy Israel, who in part is given refuge in the wilderness for the remaining 3 1/2 years.
Again, sorry this is so short. Like to put in references but I am out of time.
God bless.
