so why are we fighting??

Monday July 18th, Genesis 17: as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation. We don’t hear much about Ishmael, but Abraham loved him and so did God. In the Koran, Ishmael is the one blessed by God, maybe they are both right. Ishmael is considered the one through whom the blessing was passed down to the Arab people. Isaac the one through whom the blessing is passed down to Jesus. Both children of Abraham, both blessed. So tell me again why we are fighting, I don’t understand.
