No.
The key key element in this, is the most holy Virgin Mary.
But you can't understand that except if you are an Eastern Orthodox Christian.
I ll try to explain briefly - so I ll lose the details, but it's ok.
🔸 Catholics believe that Virgin Mary was born "differently". But that raises the question: why God haven't done that to a grandchild of Eve, let's say, so thinks won't go that far for the humanity?
🔸 Protestants believe (generally ofcourse, you can't count the churches and denominations any more) that Virgin Mary was in the "right place the right time". If God was about to choose another timeline, a different woman would have been chosen.
But this is not what Eastern Orthodox believe. Virgin Mary reached the "maximum holiness" that a human could ever reach, of course with the grace of God but also using the tradition and faith in the true God which was given to her by the Israeli culture.
How God could make his word and truth withstand in time?
God used the concept of "nation".
Nation is a conservative mechanism which seeks uniformity to the society by keeping values, language, belifs etc.
God connected the belief in him with the well-being of the nation of Israel, so ar least out of selfishness they would keep the true faith, until this could have been used in its ultimatum by Virgin Mary.
After Jesus was born things changed.
The first "enemies" of Jesus was state representatives and the Israeli customs and traditions.
After his crucifixion and death on the cross, the concept of "nations" is obsolete. There is no need for nations any more.
Apostole Paul says there is only one "nation", the "nation of Christians".
Apostole Peter also got late to realize that but he finally did.
Until today national or tribal traditions and costumes are often the "enemies" of the Christianity's expanding.
So no, we don't need to support Israel by any means.
