It may be theologically debated on rather a Christian should support Israel. However, no matter what side you take, Israel will still be prophetically standing for the Revelation events to occur. Israel should be supported politically because they are the only nation in that region that promotes human rights, religious freedom, and a Democratic system of government where the people have the freedom to vote. Their counterintelligence on terrorist organizations is crucial for national security for America and our allies. Due to our aligned beliefs on religious freedom, human rights, and defense from terrorism, many in the middle east consider Israel and America the same. Both infidels and worthy of destruction.
Theologically it is debated because some believe the Old Testament verses like this one below to be obsolete.
Genesis 12:2-3
New International Version
2 “I will make you into a great nation,
and I will bless you;
I will make your name great,
and you will be a blessing.
3 I will bless those who bless you,
and whoever curses you I will curse;
and all peoples on earth
will be blessed through you.”
This is just my interpretation, but I know for a fact that nowhere else in scripture does it counter this promise. Nowhere is it canceled. The bottom portion of verse 3 was completed in Jesus Christ as all people on the Earth were blessed through Jesus's sacrifice. As for the fulfillment of the Old Testament, this is related to the demands of the Mosaic ceremonial laws, judicial laws, and completion of Old Testament prophecy.
I do not see where the promise of I will bless those who bless you, and whoever curses you I will curse, stops from being true.
We had better be on the Jews side if we know what is good for us.
God is going to restore the kingdom on earth to the Jews in the future and nothing can thwart that.
Put it this way the whole world could attack Israel with every modern weapon they have that they can carry and they would lose and not prosper, or they could throw every nuclear bomb on the planet at Israel and they would fail to hit their target.
God will not let them go down for it has begun for Israel to reclaim all of their land.
God always restores Israel when they are punished and scattered off their land and He will do it again after they have borne their shame.
God said He is going to gather the whole house of Israel and put them back on their land and they shall know the LORD their God from that time forward and He will never hide His face from them again which means they will be in the truth from that time forward.
The antichrist will establish peace in the Middle East and it will pave the way for all Jews to go to Israel for the Gentile nations will cause it to happen and the New Age Christ wants them all back on their land but God means it for good towards the Jews to turn them to the truth.
With the conflict going on in Israel between the Jews and Palestinians it could be close to the New Age Christ to establish peace in the Middle East.
God said He will make a full end of all Gentile nations but not make a full end of Israel.
Israel is blinded in part until salvation is no longer available to the Gentiles which is when the world follows the antichrist and so all Israel shall be saved which Jesus said the Jews will not see Jesus again until they accept Him as Lord and Savior which they will do for the gifts and calling of God are without repentance on God's part.
God said if the ordinances of heaven, the sun, and the moon, and the stars are still shining then His covenant with Israel still is in affect and they will never cease from being a nation, and he has not cast away His people that he once foreknew.
God said He will gather all nations together against Jerusalem and then save the Jews and punish the world for their sins and iniquities against Him.
Which half of the city will be taken and the other half saved which because of the peace treaty the Jews split Jerusalem with the Palestinians which the world tramples on the half of the Palestinians to get to the Jews but then they are stopped as Jesus melts the flesh off their bones with the brightness of His coming.
Which God said if anybody goes against Jerusalem, the Jews, they will be cut in pieces.
Isa 31:4 For thus hath the LORD spoken unto me, Like as the lion and the young lion roaring on his prey, when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor abase himself for the noise of them: so shall the LORD of hosts come down to fight for mount Zion, and for the hill thereof.
Isa 31:5 As birds flying, so will the LORD of hosts defend Jerusalem; defending also he will deliver it; and passing over he will preserve it.
It has already begun of the Jews reclaiming their land which Israeli fighter pilots like birds flying paved the way for Israel to win the 6 day war in 1967, and took possession of Jerusalem.
Nah 2:3 The shield of his mighty men is made red, the valiant men are in scarlet: the chariots shall be with flaming torches in the day of his preparation, and the fir trees shall be terribly shaken.
Nah 2:4 The chariots shall rage in the streets, they shall justle one against another in the broad ways: they shall seem like torches, they shall run like the lightnings.
God tells us of automobiles which Nahum did not know to call them that but knew chariots is a form of transportation so we are sure in the end time.
