10In bringing many sons to glory, it was fitting that God, for whom and through whom everything exists, should make the author of their salvation perfect through suffering. 11Both the one who makes men holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers. 12He says,"I will declare your name to my brothers;in the presence of the congregation I will sing your praises." 13And again,"I will put my trust in him." And again he says,"Here am I, and the children God has given me."14Since the children have flesh and blood, he too shared in their humanity so that by his death he might destroy him who holds the power of death—that is, the devil— 15and free those who all their lives were held in slavery by their fear of death. 16For surely it is not angels he helps, but Abraham's descendants. 17For this reason he had to be made like his brothers 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. 18Because he himself suffered when he was tempted, he is able to help those who are being tempted.
Jesus was God, but also man. If we fail to remember Jesus' humanity, we end up thinking of Him as a superman who died, but barely felt a thing because He was God. That is not what the Bible teaches. Jesus shared our humanity, he was made like His brothers (us) in every way, He suffered and He was tempted. Whatever situation we are in, the God of the universe knows exactly what it is like. Even though we rebel against God, Jesus didn't. While we enslave ourselves to sin and go chasing after idols, He didn't. While we give into temptation and choose something else over God, Jesus didn't. While we allow our suffering to lead us to become bitter towards God and others, Jesus didn't. So while we deserve death for all of those things and He didn't, He died to atone for all of that stuff, so that we can live. That's our merciful and faithful High Priest.
