The Son of Man began His ministry by fasting for 40 days. At the end of the fast, the Devil approached Him with three temptation.
Again, the devil *took Him to a very high mountain and *showed Him all the kingdoms of the world and their glory; and he said to Him, “All these things I will give You, if You fall down and worship me.” (Matthew 4:8-9 NASB)
At the third temptation, Satan offered The Son of Man the kingdoms of the world if He would worship the Devil.
Note: Satan could make this offer, only if the kingdoms of the world was his to give.
This is The World System that every person on earth lives in. That is, a world that is ruled by Satan, where we unwittingly are slaves in bondage to it.
I heard another voice from heaven, saying, “Come out of her, my people, so that you will not participate in her sins and receive of her plagues; (Revelation 18:4 NASB)
