Jeremiah 31:31-33 The days are coming when I shall make a New Covenant with Israel and Judah, ….this is the Covenant I will make with the Israelites in the latter days: I shall fix My Laws in their hearts and I will be their God and they will be My people.
The Reformers of the Church generally believed and taught that the Church was Israel. Therefore; all Church members were Israelites by faith.
However they didn’t make clear who exactly the ‘church’ was and to allow anyone who wanted membership, some only after an intensive Bible course, some after a Baptism and some just if they made a donation, has led to much abuse and error within the established Church.
The Jewish people think they have the ancestral right to be God’s people and many today support them in this belief. It is an immutable tenet of the ‘rapture to heaven’ theory, where the Church goes to heaven, while the Jews face tribulation on earth.
This theory isn’t Biblical and contradicts God’s Plans for His faithful people; all those who have freely chosen to believe in Him and keep His Laws now; Jew and Gentile.
John the Baptist told the Jews; God can raise up children for Abraham from these very stones. Matthew 3:9 and Paul said: A person is not a Jew, [Israelite] who is one outwardly, but only inwardly. By the Spirit. Romans 2:29 & 11:13-24
Paul goes on to say: The Jews were cut off, because of unbelief….and Gentiles who are not Israelites by descent, are grafted in to the Olive Tree by belief in Jesus.
Only born again believers, circumcised in their hearts, confessing faith, with true repentance, like the Ethiopian eunuch, should become Church members, by full immersion Baptism as he and Jesus were.
So the established Churches [I capitalize Churches as they are known entities- bricks and mortar] cannot claim to be the congregation [ekklasia] of God. It is only every individual who is Crucified with Jesus and the life they now live is not their life, but that of Jesus who lives within them…., Galatians 2:20, who are the true Israelites of God. Galatians 6:14-16
They are people from every tribe, race, nation and language, Revelation 7:9 All the faithful Christ following people, to whom the Promises and Blessings of God come to and those who will finally fulfil God’s desire for a nation the produces the fruit of being His witnesses and the Light for the nations. Matthew 21:43, Matthew 5:14, Isaiah 43:10, Isaiah 49:8
When the letters to the seven Church types of Revelation 2:1-29 and Revelation 3:1-22 are read and understood, it will be seen that Jesus rewards the victorious or the overcomers, out of each of those Churches . This proves how not all who belong to a church or those who think their ethnicity will save them, will be saved on the Day the Lord will judge and punish the nations. Zephaniah 3:8, Isaiah 24:1-6, Revelation 6:12-17
