He is the perfect and final Priest, representing the people to God. (Heb. 2.17, 18)
Dane Ortlund
17 Therefore he had to be made like his brothers in every respect, so that he might become a merciful and faithful high priest in the service of God, to make propitiation for the sins of the people. 18 For because he himself has suffered when tempted, he is able to help those who are being tempted. (Hebrews 2:17,18)
