The Christians today are either descended from the tribes or are adopted into the family of Israel...all of Israel, not the little nation that returned in 1948. The prophecies are to (and/or) about us as well as the Jews. When we see written that there will be a time of Jacob's trouble...that will be a time of trouble for us. It will be the great tribulation in which satan comes to earth masquerading as Christ. And...he will fool the world.
Revelation 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ....that is us!
We do look at things very differently. The Tribulation period is the time God pours out His wrath upon the earth. The church is not subject to wrath. Scripture says that it will be like the days of Noah and Lot when the Lord comes. That’s a hint. What did He do with Noah and Lot? He did not protect them while they sat in the middle of wickedness. He removed them from the wickedness and then sent the judgment. There is a time where the fulness of the Gentiles comes in. You see it in Romans and in Luke. After that time, the Jews [used generically of all Israel] will be saved. The way they are saved is through His supernatural work in their lives during the great tribulation - a time that does not apply to the church, who is gone. Jews saved prior to that will be raptured with the church.
Over and over again, in Scripture, we see the promise that after many years God would bring His people back into their land. We saw that in 1948. That was a smack you in the face and open your eyes moment. That was fulfilled prophecy.
God is not done with national Israel (who has but one nation to leave in any real numbers - namely America). They will come to know Him, but they will go through a time of trouble like they have never seen. It will be horrible, but the remnant will prevail.
