It seems a general principle that no nation is entirely godless. If they refuse to worship the 
living Lord God Almighty, they will worship some other idol.1 Since Jesus is no longer welcome in much of the Western world, Isis has come to fill the void with Allah. Allah is grateful when people reject Jesus Christ the Prince of Peace, because it gives him a chance to come in.
To rid Western society of ‘religion’ (the God of the Bible’s good influence, as He is busy selecting people for His eternal Kingdom) means that some other anti-Christ deity will run to fill the spiritual void. Hardcore fighters against God and the Bible like Richard Dawkins, Lawrence Krause and Dan Barker will surely get high honours from Allah.
