The following I posted on another forum in 2011 and it covers briefly my answer to your question:
Jesus had already come way down from the glory that He had with His Father before the natural birth to a very corruptible body in Bethlehem. He had come down to the place where the dead dwelt, the realm of the natural man: hell. Everyone here who has not been born again or born from above [John 3:3] is blind to the things of God and remains "dead". As Jesus put it:
"... Follow me; and let the dead bury their dead." Matt 8:22
In the eyes of God and therefore of Jesus, anyone who could see none of the Truth of God was effectively dead! Jesus came down to this death, Himself, but being able to see and using what he had, He overcame everything that stood between Him and His place with His Father. This included His corruptible body. He also made it possible for those who had already sinned and earned the death that they were in to have Life as well:
"I am come that they might have life, and that they might have it more abundantly." John 10:10
And then today, probably many reading this will not understand or agree, but nonetheless I add yet a little more to my earlier writing.
The "earth" is what we are, a little bit of dirt/clay/mud molded by God and into which He breathed Life, as we read in Genesis. Then man disobeyed God and lost Life for him and all of his offspring. He finds himself from that point on in hell or finds hell in himself. But... be of good cheer, Jesus overcame the world of hell [John 16:33] so then God through Jesus and the Holy Spirit made it possible for us to do the same. The source of evil is where? The suffering is where?
"And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him;
Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?
And he said, That which cometh out of the man, that defileth the man.
For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
All these evil things come from within, and defile the man." Mark 7:18-23
But then Jesus came to bring Life to man again. Jesus was always even then while in hell with us also was in heaven, 1st heaven at least... Here the scripture speaks of the heavens [3]:
"And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven." John 3:13
Once we have really received Life, we need not ever be anyplace away from heaven again, but we, like the natural Israelites of old, go back into hell repeatedly, the place of death from which Jesus brought us out. How does a person descend from heaven to hell? Jesus descended on purpose to fulfill the Father's will but even Jesus asked to be relieved of that if it were possible within God's will. Down to hell he went into corruptible flesh the covering of a man in hell.
"And he went a little farther, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt." Matt 26:39
Jesus did not want to remain in hell and did not want to suffer as he did, but because it was his Father's will, he did.
