Who is the god of this world, Satan or God?
The answer to this question lies in Jesus' temptation in the desert. The devil, who is Satan, tempted Jesus three times. One one occasion, the Book of Matthew says: Mat 4:8 Again, the devil took Him up on an exceedingly high mountain, and showed Him all the kingdoms of the world and their glory. Mat 4:9 And he said to Him, “All these things I will give You if You will fall down and worship me.” Jesus, of course, rebuked him, and Satan left. But Satan made a claim that all the kingdoms of the world belonged to him. How do we know that Satan was not merely bluffing? Because it was a claim that Jesus never refuted, and he acknowledged in Matthew 12:26 that Satan has a kingdom. Moreover, Satan couldn't tempt Jesus with something he didn't have. Luke 4:1 goes into a little more detail. Satan says the kingdoms had been handed over to him. The question is, who handed the kingdoms of the world over to him? This goes all the way back to Adam. God gave Adam, and all humanity by birth...
