Talk about Jesus Christ as our High Priest, able to save us completely as He lives forever to intercede on our behalf. (Hebrews 7:25). That through His blood we have the remission of sins, and He did one sacrifice for all, for all time. He isn't like the priests of ole, having to sacrifice yearly otherwise He would've suffered since the foundation of the world (because He is the sacrifice), but He did it once, and for all sin.
Hebrews is an incredible book that really emphasizes Jesus as our High Priest, and that He truly is the Author and Finisher of our faith.
