What exactly will the Remnant Inherit and When?

The remnant during Acts were waiting for the Lord's return to the earth where they would live and reign with him.  So, they are/were not going up into heaven where the New Jerusalem remains for a time.  They were righteous and would live with Christ in the inner portion (Gen. 17).   There the Lord specifically says he will be a God to Abraham and his seed.  He did not say this regarding the outer portion, Gen.15, which was not given to Abraham himself, only his seed. Remember, the Gentiles of faith during Acts were, in Christ, and thus the seed of Abraham who would also inherit the inner portion.  It is children of the kingdom who are cast out, not the "unsaved," but rather the unrepentant Jews.

When the Lord returns there are some Israelites still alive ("in Isaac shall thy seed be called") and while these are not living and reigning, they are re-gathered (if not in the land) where they will enjoy long life, but the sinner will die at 100.  Now the outer darkness brings forth, or is where the weeping and gnashing of teeth takes place, because of the previously unrepentant seed of Isaac.  Jews thought they would celebrate "next year in Jerusalem," they said it at the close of every Passover meal so I believe.  Sad state of affairs to be cast outside the holy hill of Zion, Psalm 24.  Paul called the Corinthians "chaste virgins."  The word "meet" in 1 Thess. 4:13-18 first occurs in Matt. 25 where virgins go out to meet the Bridegroom, not the Head.   Read Matt. 24-25 and 1 Thess. 4 and 2 Thess. 2.   Some of these virgins were ready, others were not; he warned them all to watch and pray.  Then there was the guy who made it past the front door without a wedding garment, not clothed in fine linen, no access to the inner celebrations and he was speechless, thus a JEW who thought he had every right to be there, but no.

In the East the Bridegroom comes TO the Bride, never FOR her, read Jer. 30-31 and see if you can find birth pangs, the tribulation, Bride and Bridegroom dancing. nations who mistreated Israel punished (Matt.25 the righteous didn't even know they were serving Christ, Gen. 12:1-3). Weddings were celebrated in the bride's house, not the groom's.  Jer. 30-31, Matt. 24-25, 1 Cor. 15, 1 & 2 Thess.  Revelation are all the culmination of Israel's festive calendar deliverance in glorious fulfillment.

Also, does the valley of dry bones speak of a resurrection of those worthy to live in the kingdom, but not reign there? Again, the malefactor asked for the kingdom but received paradise which is way after the "kingdom."
