Horatius Bonar emphasizes the profound grace and peace that flows from the Triune God as expressed in Revelation 1:4-5. He explains that despite the perilous times, God's grace abounds even more, offering eternal grace and peace to the Church and the world. Bonar highlights the significance of the seven churches as representative of the universal Church, each reflecting different states of spiritual condition. He underscores the eternal nature of God's grace and peace, which is dispensed through the Father, the Holy Spirit, and Jesus Christ, the faithful Witness and ruler of the earth. The sermon calls believers to recognize their identity within the Church and the continuous need for God's grace in their lives.
