You were perfect up until the last sentence. God still has a plan for the Jews, and it involves the fulfillment of the promises in the OT to David, through Daniel, and the other prophets. So its not that Jews will be able to enjoy something with Christians, but rather we as Christians will be able to enjoy something God has promised the Jews.
Now, concerning the last sentence. No, non one who denies or rejects Christ will be part of the coming kingdom. But the nation of Israel will return (in the future) to God as a result of the events in the book of Revelation. One of Gods main purposes for those 7 years is to bring the Jews to repentance through the terrible events that will take place. The Jews that have lived and died since Christ, and who have rejected Christ ... are lost, just as anyone else since the time of Christ.
That the repentance of the Jews will take place in the future is foretold by Paul in Romans 11. Please read that chapter very carefully. You will understand. Especially when you read all the way down to verse 25 and 26.
What does it say ? ... It says that all of Israel will be saved ... Does that mean that those Jews who have already died rejecting Christ are saved ... NO ! ...
It means that sometime in the future, the entire nation of Israel will receive Christ. When will that happen? ...
I think it happens at the moment of the second coming of Christ ... Matt 24 talks about Christ coming in the clouds of heaven (just like in Daniel 7!) and that all the tribes of the earth shall mourn. Why will the tribes (and tribes refers to Israel) mourn? Because they will look upon him whom they have peirced and realize that He is and has always been their expected Messiah. Have you ever seen a Jew mourn? It will make any conversion we have experienced seem like Romper Room. The entire nation of Israel saved at that moment.
Now you see how we are enjoying the benefits of the Jews rejection, but when they finally receive Christ, it will be even better. Then we as Christians will enjoy the kingdom with them as His bride. The church will still enjoy a special relationship as His bride, but we will also share in the coming earthly eternal kingdom in which Christ will rule.
If what you are saying about Matthew 24 is true, then we have some nearly 2,000 year old people roaming this earth. Verse 34 says "Verily I say unto you, This generation shall not pass, till all these things be fulfilled." Matthew 24:1-34 is not in reference to the second coming of Christ. They are in reference to the desctruction of Jerusalem in A.D. 70. Starting in verse 35, and until the end of the chatper, Jesus discusses His second coming. The fact that there are two distinct events discussed in this chapter is evident with careful study.
The Israel mentioned in Romans 11:26 is referring to the spiritual Israel, or Christians. Jews will be saved just like anyone else, by believing in Christ and obeying the Gospel. There is no mention of a mass national salvation in this passage, or any others.
