I'm sorry, but this does not "cut it". You are saying that the bible specifically lays out that there is a distinction between the Church and Israel, covenantal wise for their redemption, and that for their covenant to "kick in" the Church has to be removed first. If you want this interpretation to stand, you need to provide precise verses, not just suggest books of the bible that you think might back you up. Chapter and verse, please.
I can show you Chapter and verse how I arrive at the conclusion that for redemption, regardless of nationality (Jew or Greek) people must come to Christ; in which they become one body of believers. If you think that there is more beyond that, you must show it.
But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel, and not all are children of Abraham because they are his offspring, but “Through Isaac shall your offspring be named.” This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as offspring. -Romans 9:6–8
For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. For “everyone who calls on the name of the Lord will be saved.” -Romans 10:12–13
Therefore remember that at one time you Gentiles in the flesh, called “the uncircumcision” by what is called the circumcision, which is made in the flesh by hands—remember that you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world. But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility by abolishing the law of commandments expressed in ordinances, that he might create in himself one new man in place of the two, so making peace, and might reconcile us both to God in one body through the cross, thereby killing the hostility. -Ephesians 2:11–16
You run into two problems here. First, the bible tells us that Christ IS the true Israel...Israel as she was truly meant to be.
Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ. -Galatians 3:16
Now when they had departed, behold, an angel of the Lord appeared to Joseph in a dream and said, “Rise, take the child and his mother, and flee to Egypt, and remain there until I tell you, for Herod is about to search for the child, to destroy him.” And he rose and took the child and his mother by night and departed to Egypt and remained there until the death of Herod. This was to fulfill what the Lord had spoken by the prophet, “Out of Egypt I called my son.” -Matthew 2:13–15
When Israel was a child, I loved him,
and out of Egypt I called my son. -Hosea 11:1
And secondly, when reading Rom 11, it doesn't make much sense to say that Israel was pruned off herself. The tree was cut off the tree?
No, Christ, the true Israel, the root stock, the trunk of the tree, is what holds life steady. Israel...national Israel, if they were unfaithful, as the branches were cut off Christ, and believing Gentiles were grafted in. Made one with Christ, one body, and as it says in Rom 9:6-8, we become "offspring of the promise".
But if some of the branches were broken off, and you, although a wild olive shoot, were grafted in among the others and now share in the nourishing root of the olive tree, -Romans 11:17
Clearly, here, Christ is being referred to as the olive tree.
"I will keep you from the hour of trial" is, undoubtably, an interesting verse, with lots of possible interpretations. But there is simply no way you can build a doctrine of separate timetables for separate peoples...even though they must be saved by the same thing...out if it.
Likewise with the book of Revelations...many different interpretations abound about it, but it's not what I would call probably the best bet for trying to build the basis for something like this. I mean...you could try...again...with chapter and verse please. If you think Revelation is a literal and chronological march through of events, it shouldn't be that hard, right?
But...I don't think you can do it, because I don't think there is anywhere in scripture that lays out for us this separation of both peoples, covenants in different time frames etc, that you are pushing for.
I think it's a strange juxtaposition, really. Many of the 'signs' the bible talks about are those we've always seen...but they will become more intense. Some of the 'signs'...as you say...could happen within moments of his arrival (the sky darkening, stars falling etc). We have all the verses telling us we cannot know the day or hour, and yet we're also told that as we see the day approaching we are to lift up our heads!
Sometimes I wonder if it's a bit like...when...you are expecting guests to arrive. You know that they are coming that day, but for reasons, you're not sure when...just 'that day'. And so the whole day is filled with an excited expectation...you're not sure when they'll pull up, but by golly, it's gonna be that day!
Well, with Christ, the time frame is a little different, but as Christians we can have the same assurance and expectation. And every time we see a sign...an increase of them or some such, it's like we've just heard a car drive by and our excitment level jumps a little, reminding us what we're waiting for. Sometimes its accompanied by an aching heart...when will all the hurt and suffering be over? But God has it all in his hands, regardless of all our speculations and 'to and fro-ings'. That's comforting to me.
