Every high priest selected to represent men and women before God and offer sacrifices for their sins
should be able to deal gently with their failings, since he knows what it's like from his own experience.
But that also means that he has to offer sacrifices for his own sins as well as the people's.
No one elects himself to this honored position. He's called to it by God, as Aaron was.
Neither did Christ presume to set himself up as high priest, but was set apart by the One who said to him, "You're my Son; today I celebrate you!"
In another place God declares, "You're a priest forever in the royal order of Melchizedek."
While he lived on earth, anticipating death, Jesus cried out in pain and wept in sorrow as he offered up priestly prayers to God. Because he honored God, God answered him.
Though he was God's Son, he learned trusting-obedience by what he suffered, just as we do.
Then, having arrived at the full stature of his maturity and having been announced by God as high priest in the order of Melchizedek,
he became the source of eternal salvation to all who believingly obey him.
