Robert Murray M'Cheyne emphasizes the significance of Jesus as our High Priest, highlighting His divine character, exalted position at the right hand of God, and ongoing ministry in the heavenly sanctuary. He explains that Jesus embodies the perfect High Priest, who is compassionate, eternal, and holy, and who offers a complete atonement for our sins. M'Cheyne urges believers to recognize the importance of having such a High Priest for peace, joy, and access to God, while also calling those without Him to seek His grace. The sermon encapsulates the essence of the Epistle to the Hebrews, focusing on the beauty and glory of Christ's priestly role. Ultimately, M'Cheyne reassures that through Jesus, we have a mediator who intercedes for us and carries our names before God.
