New International Version (NIV)
in heaven and on earth and under the earth,
11 and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father.
Look carefully at who will bow and confess that Jesus is Lord. Everyone in Heaven, on earth and UNDER the earth. That means fallen angels and people who died despising the Lord. There are two major differences in the confession of His precious name. One confession will be by those who love and confess Him before passing into eternity. Their reward will be eternal life with Him.
The other confession will be by those who despised Him in this life but will eventually stand before Him in judgment. Prior to eternal damnation, these people and fallen angels will bow before Jesus and confess His Lordship prior to being cast from His presence forever. What a horrifying thought.
