(Matthew 28:18) Jesus approached and spoke to them, saying: “All authority has been given me in heaven and on the earth.
(1 Corinthians 15:27) For God “subjected all things under his feet.”
According to the Washtowel, Jesus is not going to have all of Jehovah's power & authority, because he'll [Jesus] need 144,000 dead/resurrected humans to help him run the earth:
w08 5/15 p. 15 par. 14 - Jehovah has also purposed that 144,000 anointed Christians be taken from the earth and raised to heavenly life as Christ’s joint heirs associated with him in administering earth’s affairs.
