"Teaching Jehovah's Witnesses: The Holy Spirit Is a Divine Person" is a clear, compelling work that exposes the Watchtower's doctrinal errors regarding the nature of the Holy Spirit and contrasts them with the plain testimony of Scripture. The book carefully demonstrates that the Holy Spirit is not an impersonal force, as the Watchtower claims, but a fully divine person who speaks, wills, intercedes, and acts throughout both Testaments. By examining the biblical evidence in its proper context, the author shows how the internal harmony of Scripture affirms the Spirit's deity and personhood. The book also provides a robust defence of 1 John 5:7, demonstrating through textual analysis that the verse belongs in the biblical record and stands as a powerful witness to the triune unity of the Father, the Word, and the Holy Ghost.
