The role of high priest was one that had been initiatied way back in Exodus with Aaron and his sons.
The high priest was the one who offered sacrifice for the forgiveness of sins and led the worship of the people. It was a very important position, initiated by God's calling.
Not only was the author of Hebrews demonstrating that Jesus was greater than angels and greater than Moses, but now the author is laying out why Jesus trumps any of the high priests before him.
"Although he was a Son, he learned obedience through what he suffered." (verse 8)
What if there is a direct correlation between the depths of God and suffering?
What if knowing God's mercy and love in thick, life-shattering ways necessitated the agony of a cross?
For Jesus, obedience was costly.
For us, it is no different.
Suffering often plunges us into the depths of God. Why then is our cry for immediate and quick relief? For me, it is because I fear what God might reveal about me, in those vulnerable and intimate spaces. But when God redeems my fear, I discover that suffering allows God to reveal more about Himself.
Do we really believe that His way for our lives, may very well involve a cross?
