How do we know Jesus is the conqueror of death?

The certainty that Jesus is the conqueror of death is established through His actions and declarations in the Scriptures. In John 11:43-44, Jesus calls Lazarus from the tomb, showcasing His power over death and foreshadowing His own resurrection. This event serves as a vivid illustration of Christ's authority, reinforcing the belief that He has dominion over death itself. Moreover, through His resurrection, Jesus confirms His victory over both physical and spiritual death, ensuring that those who believe in Him will also triumph over death. The promise of eternal life and the hope of resurrection for believers further underscore His role as the ultimate conqueror of death.
