v8. And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
v9. Wherefore God also hath highly exalted him, and given him a name which is above every name:
v10. That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
v11. And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Our Lord Jesus Christ set an example before us. We must resemble him in His life, if we would have the benefit of his death. Notice the two natures of Christ; his Divine nature, and human nature.
Who being in the form of God, partaking the Divine nature, as the eternal and only-begotten Son of God,
Had not thought it a robbery to be equal with God, and to receive Divine worship from men.
Part of the result of Jesus being highly exalted is that all people, ultimately, will be in submission to Him. The idea may actually be better expressed by “will bow,” referring to something certain to happen.
This is including every possible being. Those “in heaven” could include angels and saints who have passed away already. Those “on earth” clearly refer to people living now.
Those “under the earth” include those who have already died and perhaps the Devil and evil spirits who must submit to the power of the Lord.
This understanding is also enhanced after looking at verse 11, which refers to every “tongue” confessing Jesus Christ is Lord to the glory of God the Father.
In the future, every being will bow before the Lord, the ultimate reward for the Lord Jesus Christ who became the ultimate servant during His time on earth.
And she shall bring forth a son, and thou shalt call His name JESUS: for He shall save His people from their sins.
