What does Luke 4:5-6 reveal about all the kingdoms of the world?

Luke 4:5 And the devil, taking him up into an high mountain, shewed unto him all the kingdoms of the world in a moment of time. 6 And the devil said unto him, All this power will I give thee, and the glory of them: for that is delivered unto me; and to whomsoever I will I give it.

When, why, and how was power over all the kingdoms of the world and their glory delivered over to the devil?

How should this truth illumine our understanding of world affairs?

How the devil used what he said in Luke 4:5-6 to tempt Jesus and Jesus’ response to that highlights the importance of the devil’s claim in Luke 4:5-6:
Luke 4:7 If thou therefore wilt worship me, all shall be thine. 8 And Jesus answered and said unto him, Get thee behind me, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve.

Could it be that the devil is lying and that, in truth, he does not have power over the kingdoms of the world?

Another alternative is that his power was given to him by God. “All Satan’s power is by permission. He has no autonomy to do anything God does not permit for infinitely wise purposes.” (John Piper)
