Why is the concept of Satan's kingdom important for Christians?

Satan's kingdom and its implications are pivotal in Christian theology as it highlights the conflict between good and evil. The passage in Luke shows Jesus acknowledging the existence of Satan's kingdom and His mission to dismantle it. This understanding is foundational for believers, as they grapple with the spiritual warfare they encounter in their lives. Without a comprehension of the opposition represented by Satan’s rule, Christians may underestimate the grace required for salvation and deliverance. The active participation of Jesus in overcoming this dark kingdom reminds Christians that their salvation is a miraculous act of divine intervention, reaffirming that it is Christ, the stronger man, who liberates His people from the grasp of evil.
