As far as Israel being "God's Chosen People" you are right, you just misidentify who they are.

Gal 4:19-31 My little children, of whom I travail in birth again until Christ be formed in you, (20) I desire to be present with you now, and to change my voice; for I stand in doubt of you. (21) Tell me, ye that desire to be under the law, do ye not hear the law? (22) For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman. (23) But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. (24) Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which engendereth to bondage, which is Hagar. (25) For this Hagar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. (26) But Jerusalem which is above is free, which is the mother of us all. (27) For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not; for the desolate hath many more children than she which hath a husband. (28) Now we, brethren, as Isaac was, are the children of promise. (29) But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now. (30) Nevertheless what saith the Scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman. (31) So then, brethren, we are not children of the bondwoman, but of the free.

There is NO hope for Jerusalem which now is (the one with the Dome of the Rock Mosque in it). We need to be looking for a new Jerusalem (which is above). Jerusalem which now is is referred to as Sodom and Egypt in Revelation!

Rev 11:8 And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.

That can't be good.

Are you expecting that the physical temple will be rebuilt with the renewal of animal sacrifices?

Heb 10:1-12 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect. (2) For then would they not have ceased to be offered? because that the worshipers once purged should have had no more conscience of sins. (3) But in those sacrifices there is a remembrance again made of sins every year. (4) For it is not possible that the blood of bulls and of goats should take away sins. (5) Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: (6) In burnt offerings and sacrifices for sin thou hast had no pleasure. (7) Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God. (8) Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; (9) Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second. (10) By the which will we are sanctified through the offering of the body of Jesus Christ once for all. (11) And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: (12) But this man, after he had offered one sacrifice for sins forever, sat down on the right hand of God;

Why would God need a "new temple" again? I guess the sacrifice of His Son was not enough? Isn't that what the renewal of temple sacrifice suggests? God is going to honor that and rest with His Shekinah in a physical Holy of Holies? As he has not formed a better dwelling place sanctified by the blood of His only begotten son?

Rev 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.

So if you partake of the first resurrection what kind of priest are you going to be Aaronic (after the Law)?
