The god of the Koran is not the God of the Bible. The Koran's god is more closely related to one of the graven images for which the people of Israel were punished for worshipping.
Allah is a deceiving spirit, certainly not the God of the Bible. Some think Allah is just a sand jinn. I think it’s Baal, myself.
This “Isa” of the Koran did not die on the cross, and did not rise on the third day. Therefore, “Isa” is the very definition of an anti-Christ.
And there stood Rick Warren, so needy of worldly approval, invoking the name of an anti-Christ, in prayer.
Delusion.
