Don't they worship the same God that Abraham worshiped? Don't Christians worship the same God Abraham worshiped?
It seems to me that both the Muslims and Christians should be Jews if they really wanted to worship the God Abraham worshiped.
It is a pity that you worship the wrong God, isn't it?
No. Not even close.
Sure, they make that claim, but it's like claiming I voted for the same president as you did and instead of showing you a pic of McCain or Obama I show you a picture of Clarabelle the Clown.
To put it simply, the God of Islam demands that I send my son against the infidel to die for him. The God of the Bible sent His son to die for me.
Jesus told us to love our enemies. Muhammad had a poet assassinated because she mocked him in verse. She was stapled to the couch in her house by the assassin's dagger while her baby slept next to her. Check into how he treated the Beni Qoreiga tribe of Jews, executing somewhere around 700 of their men and selling the women and children (about 1,000 people) into slavery.
I know you're one of those fools who says in his heart there is no God, but further attempts to claim that Christians and Muslims worship the same God will be about as credible as a claim that Hasidic Jews and Southern Baptists have the same attitude toward pork.
