God calls Israel the apple of His eye which is a term of endearment. God adds a blessing to those nations and people who bless Israel and a curse on those who curse Israel. Do those blessings and cursing's still apply?
I do not see why they don’t since God changes not (Malachi 3:6). God was seen as the husband of Israel (Jeremiah 3:14). God is evidently still concerned over Israel, saying in 2 Chron. 6:6 “But I have chosen Jerusalem, that my name might be there; and have chosen David to be over my people Israel.”
Wherever God places His name is where He still places His love. Jesus wept over Jerusalem, knowing what their fate held, as He approached Jerusalem and saw the city, “He wept over it.” (Luke 19:41) This is the very reason that God has prospered the United States of America, as being one of the few nations that have chosen to be her ally, but that seems to have recently begun to change in more ways than one. When America withdraws her support and defense of Israel, God will take His hand of blessing off of the United States.
Israel is surrounded by hostile nations and Islam that seeks her destruction. A blessing is pronounced over those who will pray for and bless Israel. (Numbers 24:9) God will never abandon Israel and in the end, Israel will be saved by God Almighty (Malachi 3:6; Romans 11:1). Since Paul commands Christians to pray for governmental authorities and leaders (Romans 13:1-7) why should we not also be praying for the peace of Israel? She is the chosen people of God.
Today there are Messianic Jews who already believe that Jesus is the Messiah. The national stock of Israel will join these Messianic Jews. Jerusalem is anything but peaceful right now. But the King of Peace is coming. Until then we are to be praying for the peace of Israel and for the King of Peace to come soon.
