The Bible speaks of principalities and powers. What does it refer to? Does it point to extraterrestrial or mythological beings, to demons or angels, to political powers or structures? This book not only gives us an unbiased answer to these questions, but it also offers a brief introduction to the Apostle Paul's thinking concerning powers and how they relate to the world, social order, and life in general within the framework of Christ's work on the cross. Furthermore, it will help us become aware of our own superstitious or mythological tendencies among many believers regarding the topic of principalities and powers.
