Allah is NOT YHWH. Allah is Satan
Jesus reveals Himself as the God of the OT who spoke to Moses and the Prophets. NOBODY knew of the Father until Jesus revealed Him
I'm sorry. I read the Old Testament, and I have a hard time seeing Yahweh as the "good guy."
He murders every person in the world in the great flood.
He murders the firstborn of all the Egyptians
he orders the murder of the people living in Canaan
He kills the baby of David and Bathsheba
He demands that Jephthah sacrifice his virgin daughter
He sends two she-bears to maul 42 children to death because they made fun of a bald prophet
Yet Muslims are as sincere in believing this diety is God as Christians are.
