How do we know Christ's victory over death is true?

The historical fact of Christ's resurrection is central to the Christian faith and is affirmed throughout Scripture. As 1 Corinthians 15:20 states, Christ is the firstborn from the dead, demonstrating His authority over death. His resurrection validates the promise that all who believe in Him will also be raised to eternal life. The fulfillment of Old Testament prophecies, such as those in Psalm 16:10, reinforces the truth of His victory, giving us a firm foundation for our hope in Him.
