God has not cast away His people. His people in both the old and new testament scriptures have always been those who believe and follow what God's Word says. In the old testament these were only those born of the flesh of the seed of Abraham and converted and circumcised gentile proselytes. In the new testament Gods Israel are all those who have been born again in the Spirit by believing and following what Gods Word says. If those unbelieving Jews were cut out choose to believed they could be grafted back in was the context of Romans 11:13-26. That also aligns with all the other scriptures that define who God's Israel is in the new covenant. That is all those who have been born of the Spirit to believe and follow what Gods' Word says.
You appear to accept a full-blown version of 'replacement theology'. This means that 'old' lsrael no longer exists in the eyes of God. Am l correct in thinking that old Israel died in the heart of God the day that new Israel was born at Pentecost? Is that your understanding?
The implication of this 'replacement' is that any prophecy that relates to lsrael after Pentecost must be about 'new' lsrael. And 'new' lsrael equates with the Church, the 'born again' believers in Christ.
At Pentecost, 120 individuals were baptised in the Holy Spirit. Another 3000 Jewish souls accepted Peter's preaching on that day. This was not a huge number, but their impact over the next few decades was extraordinary.
A small band of Jewish apostles took the Gospel to the Jews first. When the Jewish religious establishment rejected the Gospel, and distanced itself from the Christians, the Church then became, for the most part, a Gentile Church.
It's all very well saying that the Church is made up of Jew and Gentile, but when one surveys history, the Church, since the first century, has been, primarily, a Gentile Church. Jews, for the most part, have continued to live by the laws and customs of Judaism.
The fact that Jews continue to maintain a distinct cultural and religious identity is also connected to the land, Eretz Israel. This land has always figured centrally in Jewish theology, and features extensively in all the prophetic writings.
After the destruction of the temple in 70 CE, and the end of the Jewish wars, the 'diaspora' began. Jews were forced from Eretz lsrael, and they sought refuge in one land after another. For two thousand years, Jews had no homeland.
In Hosea 6:1-3, it says:
'Come, and let us return unto the LORD: for he hath torn, and he will heal us: he hath smitten, and he will bind us up.
After two days will he revive us: in the third day he will raise us up, and we shall live in his sight.
Then shall we know,
if we follow on to know the LORD: his going forth is prepared as the morning; and he shall come unto us as the rain, as the latter
and former rain unto the earth'.
What do you think this means? Is it related to the diaspora? Why should God be concerned about the return of old Israel to the land of lsrael when old lsrael is no longer in his heart?
Then we have to explain the final week of Daniel's prophecy [Daniel 9:24-27]. Daniel locates the events of this prophecy in the land of Israel, because that is where the city and the sanctuary stand.
The thing about Daniel's prophecy in Daniel 9 is that it appears to have nothing to do with the Church. It concerns old Israel, not new lsrael. New lsrael is a nation without an earthly inheritance, unless, of course, you believe that the promise to Abraham was a promise made to the Church, new Israel. In this case, an awful lot of Gentile Christians are going to be moving to the Promised Land!
If Daniel's final week takes place after the Church has been caught up with Christ in the air (the 'rapture'), then it has nothing to do with the Church age. It must be a prophecy intended for Ephraim' and Judah, or old lsrael.
Do you think that Christians are awaiting an earthly existence in the Promised Land?
