How do we know that Jesus conquers death?

The certainty of Jesus' victory over death is firmly rooted in Scripture, particularly in Hebrews 2:14-15, where it is stated that through His death, He destroyed the one who has the power of death, releasing those in bondage to the fear of death. Additionally, John 11:25-26 affirms this when Jesus tells Martha, 'I am the resurrection and the life. He who believes in Me, though he may die, he shall live.' This vital truth gives believers hope that physical death is not the end; rather, it leads to eternal life with Christ, confirming that there is no reason to fear death.
