You cannot be a bible-believing Christian and not support israel. Period.
Jeremiah 31:10 - "Hear the word of the Lord, O ye nations, and declare it the isles afar off, and say, He that scattered Israel will gather him, and keep him, as a shepherd doth his flock."
Ezekiel 37:12 - "Therefore prophesy and say unto them, Thus saith the Lord God; Behold, O my people, I will open your graves, and cause you to come up out of your graves, and bring you into the Land of Israel."
Genesis 12:3: "And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families be blessed."
In addition, Israel is the only democracy in the Middle East. Furthermore, Israel ensures that Christians, Muslims, and Jews have access to the Holy Land. When Jordan controlled Jerusalem, Jews could not pray at the Western Wall until the Israel Defense Forces freed it in 1967.
This is not about land. If you read the Bible, the war against the Jews began in Egypt thousands of years ago when Pharoah ordered that the sons of Hebrews be killed (Exodus 1:22); it continued through Haman (see the book of Esther) and through the Nazi era. And, sadly, it continues to this day through the anti-semitism that is primarily coming from Arabs and Muslims, and the godless Left. Remember: All who came against the Jews have been defeated. Where are Hittites, the Moabites, the Canaanites? They are gone, but the Israelites (now Israelis) are still here.
Christianity (and Western civilization itself) stands on the shoulders of Judaism: Our savior, Yeshua/Jesus, was Jewish; He came from the line of King David; the first disciples were Jewish; Paul, of the tribe of Benjamin, wrote a majority of the New Testament. So, it's clear that without Judaism, there is no Christianity -- literally.
When Balak, the king of Moab, wanted Balaam to curse Israel, Balaam replied, "How shall I curse whom God hath not cursed? or how shall I defy, whom the Lord hath not defied?" (Numbers 23: 8)
In John 4:22, it is noted that Jesus/Yeshua said the following: "Ye worship ye know not what: we know what we worship: for salvation is of the Jews."
