Four verses from Philippians, two from Hebrews. Each describe the voluntary act of Jesus humbling himself to the Father’s will. Each describe him as smaller, weaker or lower than his original state, and each ends in death. But as far as we are concerned, his death was his greatest moment. He tasted death so that none of us have to. Death that is separation from the body maybe, but not the death that is total separation from God. And he defeated the one with the power of death, that is the devil.
Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
(Philippians 2:5-8 ESV)
But we see him who for a little while was made lower than the angels, namely Jesus, crowned with glory and honor because of the suffering of death, so that by the grace of God he might taste death for everyone.
(Hebrews 2:9 ESV)
Since therefore the children share in flesh and blood, he himself likewise partook of the same things, that through death he might destroy the one who has the power of death, that is, the devil,
(Hebrews 2:14 ESV)
Heaven is the realm of the Godhead, earth is the realm of Satan. Jesus has light and life, Satan has darkness and death. Jesus came from heaven and entered the realm of Satan and his angels, the world of sin and death. Jesus, through his death and resurrection, defeated death, hell and the grave. He has the words of life and has defeated death. He is the light that entered darkness; and the darkness could not overcome it. Satan will be cast into the pit to which Jesus holds the key.
He did this so you and I might live. Why serve any other?
