Why is Christ's high priestly work significant for Christians?

The significance of Christ's high priestly work is multifaceted. In Hebrews 9:24, it states that Christ has entered the holy place on our behalf to appear before God, signifying that He actively intercedes for us. This means that the judgment we deserved was laid upon Him. Furthermore, His one sacrifice not only fulfilled the sacrificial system laid out in the Old Testament but also secured a relationship with God for believers, making them holy and accepted in His sight. Thus, Christians can approach God with confidence knowing that they are justified by His blood.
