Israel had already been restored to the land for centuries when the messiah arrived in Israel. His sheep there received him, whereas all of the others in Israel did not because they were not his sheep.
When Jerusalem was attacked His sheep did not bother fighting for political Zionism.
They all left for good reason.
They had found a better cause.
Philippians 3:3 For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
4 Though I might also have confidence in the flesh. If any other man thinketh that he hath whereof he might trust in the flesh, I more:
5 Circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, an Hebrew of the Hebrews; as touching the law, a Pharisee;
6 Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
7 But what things were gain to me, those I counted loss for Christ.
8 Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ
Paul counts his status as a Jew according to the flesh as "DUNG".
I think that means "crap".
