What does the Bible say about Jesus defeating our enemies?

The testimony of Scripture emphasizes that Jesus Christ has triumphed over all spiritual adversaries. As stated in Hebrews 2:14, Jesus, through His death, destroyed the one who has the power of death, that is, the devil. His affirmation on the cross, 'It is finished,' signifies that He completed the work of salvation, overcoming not just physical death, but the underlying spiritual death that sin brings. Just as King David celebrated victories over his enemies, we too rejoice in the victories accomplished by Christ, our true conquering hero, in the spiritual realm.
