Israel is not Totally Rejected

Israelites: All who follow after righteousness, all who seek the Lord…..Abraham is your father, Sarah your mother: the Rock from which you are hewn.  Isaiah 51:1-2

Leviticus 26:40-43 Even though the Israelites confess their iniquity, their own and that of their forefathers, I in My turn will oppose them while they live in the enemies land. If then, their stubborn spirit is broken and they accept their punishment in full, I shall remember My Covenant with the Patriarchs and I shall remember the Land. The Land, bereft of its rightful people will enjoy in full its Sabbaths, while it lies desolate. My people will pay their penalty in full because they spurned My statutes and judgements.

Leviticus 26:44-45 Yet, even while they live outside their Land, I will not have so rejected them as to bring them to an end and break My Covenant with them, because I am the Lord their God. I shall remember on their behalf, the Covenant that I made with their ancestors, whom I brought out of Egypt. I am Y’hovah.

Deuteronomy 30:1-5 When all these things have happened to you in the nations to which I have banished you, if you and your children turn back to the Lord and obey His commands with your heart and soul: Then the Lord, your God will restore your fortunes. In compassion for you, He will gather you again from the peoples, even from the ends of the earth. He will fetch you home, back to the land of your ancestors and you will occupy it once again. You will be more prosperous and numerous than your forefathers.

Deuteronomy 30:6-10 The Lord your God will circumcise your hearts, so that you will love Him and obey His commands, and then you will live. All the curses that you endured will be turned against your enemies, those who persecute you. He will make you more prosperous in all that you do, in your families and the produce of the Land. When you turn back to your God with all your heart, He will again rejoice over you and do you good.

The prayer of Daniel for the Redemption and Restoration of all the Israelites;

Daniel 9:4-14 Lord, great and terrible God, You keep faith with those who love You and observe Your commandments, we have sinned and rebelled against You. We have not listened to Your prophets, who spoke in Your Name to our forefathers. Lord, the right is on Your side; the shame, now as ever belongs to us, the people of Judah and to all the Israelites, near and far in every land to which You have banished them for their  disloyal behaviour toward You. All Israel has broken Your Law and refused to obey Your commandments, so that the oath and curses recorded by Moses have rained down upon us, for we have sinned against God. He has carried out the just punishments and brought upon us the disasters as foretold. Yet we have done nothing to appease the Lord, our God; we have neither repented of our wrongful deeds, nor remembered that You are true to Your Word. The Lord has kept strict watch and done what He said He would do.

Daniel 9:15-19 Now, Lord our God who brought Your people out of Egypt by a strong hand and winning for Yourself a great Name; we have sinned, we have done wrong. Lord, by all Your saving deeds; we beg that Your wrath and anger depart from Jerusalem and Your Land. Listen, our God, to Your servants prayer and supplication for Your sake, Lord look favourably on Your sanctuary that is desecrated. God, incline Your ear to Your people, and hear us, we pray. It is not because of any righteous doings of ours, but because of Your great mercy that we lay our supplication before You. Lord; hear, Lord; forgive, Lord; listen and act, God for Your own sake do not delay, for reputation of the city and for the people that bear Your Name.  

Acts 26:6-7 In the hope based on the promise God made to our forefathers, all twelve tribes of Israel worship with intense devotion, looking forward to the fulfilment of that promise.                                               Reference: Revised English Bible. Some verses abridged.

Since Jesus came and extended salvation to all who would accept it, every Christian is an Israelite of God. Galatians 6:16  Every faithful Christian is a holy child of God.
