What does Hebrews 2 teach about the devil's power and Christ's victory?

In Hebrews 2:14-15, we learn that the devil had the power of death and that through His own death, Christ rendered the devil's power inoperative. This victory is foundational to Christian hope, as it signifies the defeat of sin and death. Through His sacrificial death on the cross, Jesus ensures that believers are no longer captives of the devil but are liberated and brought into a new life in Him. The culmination of this victory allows Christians to approach God without fear, knowing that Christ has secured our eternal salvation.
