What does Revelation teach about spiritual warfare?

The book of Revelation unveils the ongoing spiritual battle between good and evil, with the opening of the seals depicting the reality of spiritual oppression and warfare faced by believers. Each seal broken by the Lamb reveals increasing calamities authorized by God to serve His redemptive purposes. As these seals represent different aspects of human suffering, they also remind Christians that the ultimate victory belongs to Christ, who reigns over all spiritual forces. Despite the struggles faced, believers are reassured that they are victorious in Him, as their suffering leads to glory.
