Pastor walks his children through Westminster Shorter Catechism question 89—especially explaining how God uses His Word in every part of saving us. Q89. How is the Word made effectual to salvation? The Spirit of God maketh the reading, but especially the preaching, of the Word, an effectual means of convincing and converting sinners, and of building them up in holiness and comfort, through faith, unto salvation. The sermon explores the vital role of the Holy Spirit in making the Word of God effectual for salvation, emphasizing that reading and, particularly, preaching are transformed into instruments of conviction, conversion, and spiritual growth through divine agency. Drawing from Romans and 2 Timothy, it highlights how the Law reveals our sin and exposes us to God's wrath, while the Gospel proclaims Christ as a propitiation, justifying those who believe. Ultimately, the Spirit softens hearts, implants the Word, and empowers believers to live a life of holiness, comfort, and mercy, demonstrating that salvation is not achieved through human effort but through God's grace and the transformative power of His Spirit.
