I’ve never been told this directly, but I’ve been told it before.
I always remember that God blessed both Isaac (Jews) and Ishmael (Arabs/Palestinians).
I believe that the Lord knew that at some point this doubt would come to people’s hearts and He made sure to say that Ishmael’s people were also blessed.
Supporting Israel will never mean supporting only the Jews and despising the Palestinians. Quite the opposite, it means ensuring that both will live in peace.
The Palestinians have suffered as much (or even more) than the Jews and that’s why our fight is not against the Palestinians, but against the oppressive and terrorist group that has done this to the Palestinians and Jews, Hamas.
It’s also worth remembering that this war, although physical, is also very much involved in the spiritual world.
I believe I would explain these things and talk about the importance of studying, praying and loving these people, Jews and Palestinians (Arabs), Christians and Gentiles…
And any and all others, condemning and bringing justice to their oppressors.
