7In this book, Clarence Larkin explains the various elements of the spiritual world of Christianity; including demons; the underworld; resurrection; and man's relationship to the spirits. Unafraid to tackle topics often ignored or relegated to the barest mention by other theologians, in The Spirit World Clarence Larkin delves deeply into the topics such as hell, Satan and demonic manifestations. His accessible style is made further comprehensible by the myriad drawings and charts, which visually portray concepts which first appeared in the Bible. For decades in his role as a preacher and theologian, Larkin immersed himself in the depths of Biblical lore. His studies ranged from explaining obscure or cryptic books of the Bible, to clarifying the manifestations of spirits good and evil, and how these corporeal beings interact with one another and with humans. The machinations behind phenomena such as resurrection, fallen angels and the journey of the soul to the afterlife are topics which Larkin explains.
