How do we know that Christ has defeated sin and death?

The victory of Christ over sin and death is firmly established in the Scriptures. Hebrews 2:14 states that Christ, by His own death, destroyed the one who holds the power of death, which is the devil. Additionally, 1 Peter 2:24 explains that Christ bore our sins in His own body on the tree, enabling us to live to righteousness. These passages collectively illustrate how His sacrificial death and resurrection procured our freedom from sin's power, making Him the ultimate Breaker who liberates His people.
