No worries, Lizbeth. It is hard to keep up.
I'm sorry to bring this up again, but it is important. As I noted before, the Scriptures do not state that Israel was an "ensample" to us. The disobedience of the people in the wilderness under Moses was the example to those of that day, not to us. We can surely draw an application, but that is not the context of that passage. The example was not Israel; it was those in the 40-year wilderness wanderings.
When is the "time of the Gentiles"? You will probably disagree because, like all futurists, you do not accept Jesus' meaning of "this generation." He used that expression 19 times, and He always meant those of His day, His contemporaries. Jesus stated that the "times of the Gentiles" would occur in that very generation of those disciples standing right there with Him. If we consider Daniel's timing, we find this fits the years leading up to the destruction of Jerusalem and the Temple in A. D. 70. During that time, God allowed the Romans to "trod down the city of Jerusalem for the time of its destruction. "Time, times, and half a time (1260 days, 42 months, or 3 1/2 years) coincides perfectly with the time frame of the Roman-Jewish wars--A. D. 67 - A. D. 76 (1260 days, 42 months, 3 1/2 years!). The times of the Gentiles ended at the destruction of the Temple and the city in A. D. 70. Lizbeth: "This generation" means exactly what it means. The answers to your questions lie in that time frame. Approaching this any other way will give you more questions than answers. Will you consider it?
Whatever horrors and calamities are happening in the world right now are nothing much different than those of most past generations. We must refrain from using "newspaper exegesis" whereby we impose things happening today upon the scriptures. The bottom line is that the things Jesus warned about on the Mount of Olives were directed at those very disciples right there with Him. The wars and rumors of wars were of their day. They were to be killed and hated for His name's sake. And they were. They were to see the Abomination of Desolation spoken of by Daniel the prophet (the surrounding of Jerusalem by armies--Luke 21). They were to flee. History records that when Christians, heeding Jesus' words and the words of the inspired writers, fled the city to the mountains of Pella. All were saved from the coming assault on the city.
First Corinthians 15 is not about physical bodies coming up out of the grave. That is not Paul's point. Notice that it is not the seed (i.e., the physical body) that comes forth from the grave. The seed dies and returns to the dust of the earth, where it remains. The physical body is good, but it is fitted for this world only. We must be given a "new body" that is fitted for heaven. That which comes forth is not like the seed. At the New Birth, we are made a new creation. But before Christ's return as the Great High Priest, having exited the heavenly Holy of Holies in full satisfaction of God's wrath against sin, no one was yet fitted for heaven. As taught by the writer of Hebrews, Christ came the first time to deal with sin (the Cross). He would come a Second time for "salvation" (Heb. 9). What salvation? Believers at that time were saved in that their newness of life was assured; nothing could change it. But it was THEY who were sealed with the Holy Spirit of promise. We no longer need to be sealed because the promise has come. What was the promise? Full salvation that allowed them to, at death, go immediately into God's presence instead of going to Hades to await resurrection.
Jesus told His disciples right there with Him that when THEY saw all of those things begin to happen, THEY were to look up. Why? Because THEN their salvation drew near. They were already "saved" (and sealed), but at His coming, they would be resurrected to full communion with God. This is resurrection! Paul taught this as well. Writing to the saints at Rome, he said: "The hour has come for you to awake from sleep. For salvation is nearer to us than when we first believed. The night is far gone, the day is at hand" (Rom. 13:11, 12). They were saved and sealed, but full salvation awaited them (it was AT HAND in their day). It was that which Paul taught in 1 Corinthians 15--that which came to them in A. D. 70 at the comi;ng of the Lord. Hades, the waiting place, was emptied of the "dead ones" (1 Thess. 4).
Who is Israel, Lizbeth? Since Christ came and broke "down the middle wall of partition" between Jew and Greek and made of them ONE NEW MAN, true Israel consists of both Jew and Gentile--both reconciled to God in ONE BODY (Eph. 2:11ff). Paul made this clear when he stated that one is a Jew who is one inwardly. Spiritual Israel, made up of the spiritual seed of Abraham, is circumcised in the heart and not in the flesh. God judged OT Israel once and for all in A. D.. 70. That nation is no more. The nation that calls itself Israel today is a creation of the U. N. and not of God. They are not OT Israel.
The Bible contains many types and antitypes. OT Israel, fleshly circumcision, the Temple, the priesthood, the sacrificial system, the altar, Jerusalem, the land, etc. are all types that have been done away with in the one New Body of both Jew and Gentile (the Church), circumcison of the heart, the spiritual temple, the priesthood of believers, the once-for-all sacrifice of the Lamb of God, the heavenly holy of holies and altar, the New Jerusalem, the kingdom [land]. These are all antitypes. That physical land in the Middle East today is of no biblical consequence.
You wrote: "But now we do not yet SEE all things put under him." Lizbeth, I would encourage you to please pay close attention to the context of passages you refer to and acknowledge the identity of the "we" and the "you," etc. WE are not the WE of Hebrews 2:8. The writer of Hebrews is addressing those of his day. They are the WE. In their day, THEY had not yet seen all things under His feet. But they would. When He came "in a VERY, VERY LITTLE WHILE" (Heb. 10:37) to them.
