Horatius Bonar expounds on Revelation 21:9, illustrating the Church's dual identity as both the bride and the wife of Christ. He emphasizes the Church's humble beginnings as an unlovable outcast, chosen by the Father and redeemed by the Son, who undertakes to free her from sin and death. Bonar highlights the preparation and adornment of the Church by the Holy Spirit, culminating in the glorious future marriage to the Lamb. He invites all to accept the proposal of this divine Bridegroom, urging them to embrace the honor of becoming part of the Lamb's wife. The sermon concludes with a call to recognize the boundless love of God that transforms the redeemed into heirs of His glory.
