God cannot establish His Son in Israel as King of the Jews unless the Jews are living in Palestine, their promised homeland, so it is God's plan to restore the Jews to Palestine before the Second Coming of Christ:
"But, The LORD liveth, that brought up the children of Israel from the land of the north, and from all the lands whither he had driven them: and I will bring them again into their land that I gave unto their fathers." (Jer. 16:15)
"And I will bring again the captivity of my people of Israel, and they shall build the waste cities, and inhabit them; and they shall plant vineyards, and drink the wine thereof; they shall also make gardens, and eat the fruit of them. And I will plant them upon their land, and they shall no more be pulled up out of their land which I have given them, saith the LORD thy God." (Amos 9:14-15)
Since Israel rejected Christ, God allowed the Romans to destroy Jerusalem in 70 A.D., and the Jews were dispersed among the Gentile nations of the world. Since then they have wondered from nation to nation suffering bitter persecution. However, in the late 1800's a remarkable thing started happening. In large numbers, the Jews began returning to Palestine, and in 1887 they made formal statements that they intended to REPOSSESS THEIR HOMELAND!
When World War I began in 1914, there were 80,000 Jews living in Palestine. England's Balfour Declaration of 1917 gave strong approval for the Jews to establish a national homeland, but England reneged due to Arab pressure. Nevertheless, 400,000 Jews had settled in the homeland by 1939.
Satan saw what was happening. He knew that the Lord was re-gathering the Jews for a reason, and he knew the reason: the Second Coming of Christ. So Satan raised up Adolph Hitler to murder six million of God's chosen people as an outright act of hate and revenge. This massive slaughter created enough sympathy for the Jews that the United Nations granted 5000 square miles of Palestinian land to them after World War II. Then in 1948 Israel became an independent nation for the first time in many centuries! The Arabs have fought viciously to destroy Israel, but with no success. God wants His people IN PALESTINE (Amos 9:14-15), because the Lord Jesus Christ is coming very soon. During the Six Day War of 1967, Israel even gained possession of the ancient temple sight, and plans are currently underway to rebuild the temple.
Jesus likens Israel unto a "fig tree" in Matthew 24:32-34, and He likens the restoration of Israel unto a fig tree putting forth leaves. He said that He would return during the same generation which witnesses Israel putting forth leaves as a nation. We are living in that generation! There are some four million Jews living in Palestine today. We have seen the Jews return to Palestine, and we have seen the nation of Israel prosper.
