Hebrews 5-7 introduces a second function of Jesus. He is our High Priest. The author explains that this fulfills a promise God had made to the promised Davidic king, that He would be “a priest forever according to the order of Melchizedek” (Ps. 110:4, as quoted in Heb. 5:5, 6, NKJV).

 Read Leviticus 1:1-9, Leviticus 10:8-11, Malachi 2:7, Numbers 6:22-26, and Hebrews 5:1-4. What functions did the priest fulfill?

 The priests were appointed on behalf of human beings to represent them and mediate their relationship with God and the things pertaining to Him. The priest was a mediator. This was true of any system of priesthood, whether Jewish, Greek, Roman, or any other. The priest makes it possible for us to relate to God, and everything the priest does has the purpose of facilitating the relationship between us and God.

 The priest offers sacrifices on behalf of human beings. The people cannot bring these sacrifices to God in person. The priest knows how we can offer an “acceptable” sacrifice so that our gifts may be acceptable to God or that they can provide cleansing and forgiveness.

 Priests also taught the law of God to the people. They were experts in God’s commandments and were in charge of explaining and applying them.

 Finally, the priests also had the responsibility of blessing in the name of Yahweh. Through them, God mediated His goodwill and beneficent purpose for the people.

 However, in 1 Peter 2:9, we see something else. We — believers in Jesus — are called “a royal priesthood.” This role implies incredible privileges. Priests could approach God in the sanctuary. Today, we can approach God through prayer with confidence (Heb. 4:14-16; Heb. 10:19-23). There are, as well, important responsibilities. We must collaborate with God in His work of saving the world. He wants us to teach and explain God’s laws and precepts to others. He also wants us to offer sacrifices of praise and good works, which are pleasing to Him. What a privilege and what a responsibility!
