Behold, I have come to do YOUR WILL... in THAT WILL, we have been made holy through the offering of the body of Jesus Christ... Hebrews 10:9-10

For it was fitting for HIM, for whom are all things, and through whom are all things, in bringing many sons to glory, TO PERFECT the author of their salvation through sufferings. Hebrews 2:10

In the days of his flesh, he offered up both prayers and supplications with loud crying and tears to the One able to save him from death, and He was heard because of his piety. Although he was a son, he learned OBEDIENCE from the things which he suffered and having been MADE PERFECT, he became the source of eternal salvation to all those who obey him
Hebrews 5:7-9

If I glorify myself, my glory is nothing. It is MY FATHER who glorifies me. John 8:54,

I can do nothing from myself. As I HEAR, I judge, and my judgment is just, because I do not seek my own will, but the WILL OF HIM who sent me.
John 5:30

Sacrifice and meal offering You have not desired. My ears YOU HAVE OPENED. Burnt offering and sin offering You have not required. Then I said, “Behold, I come; In the scroll of the book it is written of me. I delight to do YOUR WILL my God. Your Law is within my heart.”
Psalm 40:6-8

Therefore, when he comes into the world, he says, “Sacrifice and offering You have not desired, but a body YOU HAVE PREPARED for me.  In whole burnt offerings and sacrifices for sin You have taken no pleasure. Then I said, ‘Behold, I have come (In the scroll of the book it is written of me) to do YOUR WILL, O God.’” After saying above, “Sacrifices and offerings and whole burnt offerings and sacrifices for sin You have not desired, nor have You taken pleasure in them” (which are offered according to the Law), 9 then he said, “Behold, I have come to do YOUR WILL... in THAT WILL, we have been made holy through the offering of the body of Jesus Christ...   Hebrews 10:5-10

He was bodily God prepared, God equipped, God fitted. See also Greek katartizō.
