In bringing many sons and daughters to glory, it was fitting that God, for whom and through whom everything exists, should make the pioneer of their salvation perfect through what he suffered. 11 Both the one who makes people holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers and sisters. 12 He says,

“I will declare your name to my brothers and sisters;
    in the assembly I will sing your praises.”

13 And again,

“I will put my trust in him.”

And again he says,

“Here am I, and the children God has given me.”

14 Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death—that is, the devil— 15 and free those who all their lives were held in slavery by their fear of death. 16 For surely it is not angels he helps, but Abraham’s descendants. 17 For this reason he had to be made like them, fully human in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people. 18 Because he himself suffered when he was tempted, he is able to help those who are being tempted.

It seems to me that verse 11 forms the text for the remainder of the chapter.

Jesus had to become a human being in order to rescue humans from their slavery to the fear of death, and in order to represent them before God as their Priest.

We need the perfect God-Man to fully save us, and to perfectly understand us (see 4:14-16).

Still today there is a Man in heaven. What Jesus became in the Incarnation He did not unbecome in His Ascension.

”Therefore he is able to save completely those who come to God through him. He lives forever to intercede with God on their behalf” (Hebrews 7:25).

Someone said, ‘You’re on Jesus’ prayer list. That ought to make your whole day.’
