Why is Jesus considered the Great High Priest?

In Hebrews 4:14-16, Jesus is portrayed as the Great High Priest who has passed into the heavens. His role is vital because He understands our weaknesses, having been tempted in every way yet without sin. This qualification enables Him to intercede effectively for His people. Unlike the Jewish high priests who had to offer sacrifices repeatedly, Christ offered Himself once for all, securing eternal redemption. Therefore, believers are encouraged to approach the throne of grace boldly, confident in the advocacy of Christ, who understands our struggles and offers mercy and help in our time of need.
