Luke 4:6, Who Has Dominion Over The Earth?

And the devil said unto [Jesus], 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.

//In this verse, Satan makes a bold claim: that he has dominion over all the nations, and has the power to grant that position to Jesus. However, Matthew claims just the opposite in his gospel:

And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth –Matthew 28:18
