Wow. Abraham was a single source for three of the worlds largest religions. His 1st son by Hagar (his servant) was Ishmael. He founded the Islamic faith.
His son by Sarah (his wife) was Isaac. He founded the Jewish faith.
So why do these two faiths hate each other? Why is there so much spilled blood? Does it all go back to a brotherly dispute? Ishmael and his mother Hagar were send out into the desert after Sarah had Isaac. Was there more to the story? The lord of Ishmael and Isaac are the same. We are all brothers and sisters.
