What does it mean that Christ is our great high priest?

In Hebrews 4:14-16, Jesus is described as our great high priest who has passed into the heavens. This title signifies His role as the mediator between God and humanity. Unlike the earthly priests, who offered sacrifices repeatedly, Jesus offered Himself once for all, providing a complete and perfect atonement for sin. Therefore, Christians can confidently approach the throne of grace, knowing they are welcomed and heard. His sympathetic intercession ensures that He understands our weaknesses and offers us the mercy and grace we need in times of trouble.
