What does it mean that Jesus is our high priest?

In the context of Hebrews, Jesus as our high priest signifies His role as the mediator between God and humanity. Hebrews 10:21 states, 'And having a high priest over the house of God,' which highlights Jesus’ everlasting priesthood established through His sacrificial death. Unlike the Old Testament priests, who offered repeated sacrifices, Jesus provides a once-for-all sacrifice that fully atones for our sins. This establishes a new covenant, allowing believers direct access to God through faith in Christ's redemptive work.
