Andrew Bonar expounds on the significance of the scapegoat in the Day of Atonement, illustrating how it represents both God's satisfaction with the sacrifice for sin and the removal of guilt from the sinner's conscience. He emphasizes that the first goat symbolizes God's acceptance of a substitute, while the second goat, the scapegoat, carries away the sins of the people into the wilderness, signifying their complete removal. Bonar draws parallels to Christ, who bore our sins and suffered alone, ensuring that believers can find peace knowing their sins are forever gone. The sermon highlights the dual aspects of atonement: God's justice and mercy, and the assurance of a cleansed conscience for the sinner. Ultimately, Bonar encourages believers to rejoice in the truth that their sins are removed as far as the east is from the west.
