No one knows how many Christians have been given a love-burden for Israel and the Jewish people, but it is safe to say that there have never been as many before as there are today.
There has probably always been a small minority of "intercessors"; such as the ladies group in Hamilton, Ontario which was in deep intercession for the Jewish people throughout most of this century; but admittedly the re-creation of the modern state of Israel in 1948 caused not only theological earthquakes, but more importantly a vast multiplication of Christian groups quickened by the Spirit in order to be activated in "comforting" (Isaiah 40:1-3), and in being "watchmen":
" I have made you a watchman for the house of Israel; therefore you shall hear a word from my mouth and warn them for Me" ( Ezekiel 33:7)
The "International Christian Embassy, Jerusalem" is one such ministry and it can certainly be said, without belittling any other group, that it has the highest profile both among the Jewish people in Israel, and officially among more than one hundred nations. This whole trend is a sovereign work, at a "set time", prior to Israels "return to the LORD":
" O ISRAEL, return to the LORD your God, For you have stumbled because of your iniquity; Take words with you, And return to the LORD. Say to Him, "Take away all iniquity; receive us graciously...." (Hosea 14: 1-2)
As "Christian-Zionists" we understand that God is still keeping covenant with collective "Israel", but that they have not yet entered into the "new heart covenant" promised to "the house of Israel, with the house of Judah..not according to the covenant that I made with their fathers...which covenant they broke though I was a husband to them says the LORD" (Jeremiah 31:31,32)
Their return to the land is a forerunner of their return to their God:
"they said of them, These are the people of the LORD, and yet they have gone out of His land....But I had concern for My holy name,....Therefore, I do not do this for your sake O house of Israel, but for My holy name's sake...And I will sanctify my great name when I am hallowed in you before their eyes....For I will take you from among the nations, gather you out of all countries, and bring you into your own land....THEN I WILL sprinkle clean water on you and you shall be clean.
...I will give you a new heart and put a new spirit within you...and cause you to walk in My statutes......Then you shall dwell (remain) in the land that I gave to your fathers;
YOU SHALL BE MY PEOPLE, AND I WILL BE YOUR GOD" (Ezekiel 36:20-28)
The only "unknown" in this is the timing ! Our part is to be faithful to our call to be "Watchmen", "Comforters" and "vessels of Mercy" in a world which is particularly unmerciful to the Jewish people and Israel; thereby being witnesses and living lives that are a testimony, and ultimately "provoking them to jealously" as instructed by Paul. (Romans Chapter 11)
Lord God of Israel, our God, grant us the grace to so be, and so do !
