Why is having a high priest important for Christians?

In the sermon, the preacher emphasizes the crucial role of Christ as our high priest, stating that without a high priest, we have nothing. Ezra recognized the absence of a Levite among the returnees, symbolizing the need for atonement before God. Hebrews 4:14-16 affirms that we have a great high priest who has gone through the heavens, Jesus the Son of God, who can sympathize with our weaknesses and intercede for us. This highlights that our salvation and relationship with God depend entirely on the work of Christ, who mediates between us and the Father, fulfilling the sacrificial requirements of the law on our behalf.
