It seems you are stating that because present national Israel, that is not currently under the old covenant with God, is unfaithful and unbelieving, that God's promises are yet to be fulfilled, ie: no atonement for sin by the cross just yet, not putting away of sin by the cross just yet......
There is only one way to be saved, and Israel, Jerusalem, have not received it yet. It will not be until the middle of the 7 years, that Daniel's people Israel, and Jerusalem receive salvation and the kingdom.
It tells you in Revelation 12, that is going to happen after the 1260 days in Revelation 12:6, followed by the war in heaven and Satan cast down...
9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
Satan accuses the Jews, Israel, of rejecting Christ day and night, of their sins, which they have not received his shed blood to wash them away. But in the middle of the 7 years, they turn to Jesus, and have the testimony of Jesus.

Jesus returns to rescue the Jews in Zechariah 14. And he destroys those armies in Ezekiel 39:17-20.
And is speaking in Ezekiel 39:21-29. Who is Jesus talking about in those verses - the church or another group? It is easy to see He is not talking about the chruch.
