Answer #13

              Jesus was given oversight over heaven and earth; all things were subjected to him.  (1 Corinthians 15:27)  Since Jehovah is the ruler of the universe and Jesus was sitting on His throne, then his ruler ship would then not be unending.  He would, after completing Jehovah’s will for him, have to return universal ruler ship back to Jehovah  (verse 28).  The specific length of time that Jesus rules is not stated in the scriptures.
