Ezekiel 37:11 The whole house of Israel. This is a physical resurrection, Ezekiel 37:7,8,10 Ezekiel 36 and 37 are during the millennium, after the return of Christ. This is when carnal Israel will be grafted back into the church. Roman’s 11 is not about salvation but the church, the olive tree. Jesus said, Matthew 23:37,38,39 After Pentecost then it became the time of the Gentiles. Ephesians 3:1,2,3,4,5,6 Read my post about how the name of Israel was put on the church. There is no replacement theory because the Church has always been GODS true people. Romans 8:14 Romans 9:8 Moses told Israel about the tribulation. Deuteronomy 4:30KJV There is this day a veil on the heart of Israelites.
King David rules over a converted Israel. The 144000 is indeed the church before and after Christ, composed of former Israelites and Gentiles. After the great deceptions came and the rise of thousands of false churches the truth of GOD was cast to the ground. GOD knew this would happen and after the death of John took over completely the operation of the church. Is not the the church the first fruits, the redeemed. The church is the Israel of GOD the true children of Abraham, not Israel after the flesh. Abraham, Isaac and Jacob will enter the kingdom but Carnal Israelites cast out. The last will be first and the first shall be last. Your view is similar to Esau selling his birthright except you are giving it away. The church has always been the Israel of GOD , the first fruits, the called and chosen, the saints and true children of GOD . Romans 11:23 is saying that if Israelites repent they can be grafted in but for the most part, 2 Corinthians 3:14,15 has been the attitude of Israelites. Romans 11:7 Romans 9:18 Romans 11:25. The blindness of Israelites remains until the fullness of the gentiles come to Christ. The 144000 will , in the last days , be composed of a majority of Gentiles. Most of the 144000 are dead but there is to be some who are alive and remain when Jesus returns.
