Some people believe the Church replaces Israel but this is not true.
Israel is the Church, and it is Israel all the way.
From Abraham to Israel as a nation to Jesus to the millennial reign of Christ to the New Jerusalem it is Israel all the way.
That is why the 12 tribes of Israel and the 12 apostles of the Lamb are written in the New Jerusalem and it is called the New Jerusalem because it is Israel all the way.
God said He has not cast off His people He once foreknew.
God said if the ordinances in heaven the sun, moon, and stars are still operating then Israel shall not cease being a nation, and He will not cast them off.
God said He would gather the whole house of Israel back to their land and turn them to the truth that Jesus is their Lord and Savior and the kingdom will be restored to Israel and they would know the LORD their God from that time forward and He will never hide His face from them again.
God always restores Israel and He will do it again.
When the New Age Christ establishes peace in the Middle East it will pave the way for all Jews to go to Israel for the Gentile nations will cause it to happen because they came together with a global government and they will eventually rebel against God, and the New Age Christ wants them all back on their land, but God means it for good towards the Jews.
Israel is blinded in part until salvation is no longer available to the Gentiles and so all Israel shall be saved which the kingdom will be restored to them, and God said He would make a full end of all the nations governments but will not make a full end of Israel although they will be wholly unpunished.
Israel is the Church and there is Jews that confess Jesus as Lord and Savior and God will not blame all Israel for the people that did not confess Him like God will not blame all the Gentile for the people that do not confess Jesus.
Jer 31:34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
Jer 31:35 Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name:
Jer 31:36 If those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever.
Jer 31:37 Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD.
Act 1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
Act 1:7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Rev 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Rev 21:12 And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel:
Rev 21:13 On the east three gates; on the north three gates; on the south three gates; and on the west three gates.
Rev 21:14 And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.
Israel shall never cease from being a nation that started on earth and will be the New Jerusalem and spiritual place.
Israel is the Church and the covenants are with them and the Gentiles got to be included.
