Jesus is the better high priest. The author of Hebrews lays out a very meticulous argument in this regard. There is no way I can adequate condense all the argument in a blog like this. But the conclusion is clear in 7:27 and 28: Jesus is the “once for all” sacrifice due to God’s oath (promise) that the Son would be the “perfect” priest “forever.”
And in the blog today, I want to concentrate on this idea of the irrevocable promise of God’s oath that is described in 6:13-20. Our faith is founded on the certainty of God’s promise (oath) of which Christ’s coming, dying, and rising from the dead is the evidence. He is the great high priest that takes our sin and offers a sacrifice (enters the holy of holies) on our behalf so that our sins are forgiven and we have access to God (Rom. 5:1-5).
The author compares the oath of God with the oaths of humans. A human person swears by someone greater than himself or herself in order to assure delivery (vss. 13 and 16). For God there is no one greater to swear by (vs. 13). But verse 17 says that God wanted to “make the unchanging nature of his purpose very clear to the heirs of what was promised.” Unchanging and clear, that is what God wanted to communicate about what he had promised. So what did God do? Verse 18 -20 says that he did this (communicated his promise) by two unchangable things–God’s promise (in and of itself sure) and God’s oath. Because it is impossible for God to lie, his oath reinforces the unchangeability of his word or his promise. Abraham received his promise and this was the Old Testament corallary to the promise of Christ. Abraham received his son, born to his barren wife, offered as a sacrifice and delivered from death. So, too, we have received the promise of THE Son, born to a virgin, offered as a sacrifice and delivered from death, not by interruption of the sacrifice (like Isaac) but by resurrection from the grave!
And so the author of Hebrews says that we who take hold of this hope (salvation found in Christ’s death and resurrection) have an “anchor for the soul, firm and secure” and we can be “greatly encouraged” by this (vs. 18,19).
Wow! God has promised and made an oath to help us understand how sure our hope is. What he has said, he will do! Those who put their faith and trust in Christ WILL receive eternal life and be heirs together with Christ of all of the riches of God’s rule and reign for eternity. Now that’s worth hoping for!
