Jesus is the Great High Priest because He serves as the ultimate mediator between God and humanity. In this role He serves as both the priest and the sacrifice that atones for sins once and for all. But we are still called to be priests for each other. These are not mutually exclusive ideas.

Whenever you share a cup of cold water in Jesus’ name or pray for someone, you’re a priest. You’re communicating the grace of God. There are times that we need a priest, too, right? If we are to be like Him, we must allow someone else to be a priest for us. There are problems so great and pains so deep and sins so intractable that we need a person of flesh and blood to join us in carrying our concerns to God.
