Israel (Isaac) has been hated by the Arabs (Ishmael) ever since Isaac was born, the true child of Promise. Ishmael has been throwing rocks for whatever time window you choose to believe .. personally, I'll say about 4,000 years.
The rocks have gotten more severe and the warfare more devestating.
Tell your friend to pray for the peace of Jerusalem and look for His second coming.
She loves to say, "as if God needs our help to save Israel" or something to that effect.
Great recap and advice!
