Books from Geek Slop Publishing

Living Truth Bible Study Guides

Despite its beautiful prose, you can’t just read Revelation; it requires diligent study. However, ineffective study techniques can lead to misunderstandings. Rather than imposing strict interpretations on the described events, use the concepts we present as a framework for understanding its intricate code. The Book of Revelation indeed provides more than just a foretelling of the tumultuous end of days. It reassures Christians that divine justice will ultimately triumph over evil and promises Jesus' eventual return as the rightful king of the world.

Chronicles of Enigma

While science and reason often seek to illuminate the unknown, there remains a certain allure in the unexplained—a realm where imagination and reality blur, creating a tapestry rich with wonder and possibility. Stories from the Chronicles of Enigma series endure not just as relics of the past, but as gateways to exploring the depths of our curiosity and the infinite potential of our world. Let us be the light that guides you through the darkness.
