Hebrews 4:14-16; Hebrews 5:1-10
Therefore, since we have a great high priest who has gone through the heavens, Jesus the Son of God, let us hold firmly to the faith we profess.
For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are--yet was without sin.
Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need.
Every high priest is selected from among men and is appointed to represent them in matters related to God, to offer gifts and sacrifices for sins.
He is able to deal gently with those who are ignorant and are going astray, since he himself is subject to weakness.
This is why he has to offer sacrifices for his own sins, as well as for the sins of the people.
No one takes this honor upon himself; he must be called by God, just as Aaron was.
So Christ also did not take upon himself the glory of becoming a high priest. But God said to him, "You are my Son; today I have become your Father. "
And he says in another place, "You are a priest forever, in the order of Melchizedek."
During the days of Jesus' life on earth, he offered up prayers and petitions with loud cries and tears to the one who could save him from death, and he was heard because of his reverent submission.
Although he was a son, he learned obedience from what he suffered
and, once made perfect, he became the source of eternal salvation for all who obey him
and was designated by God to be high priest in the order of Melchizedek.
