How do we know that resurrection is true?

The resurrection is not merely an abstract concept but is firmly rooted in the historical event of Christ's resurrection, as recorded in the Gospels and expounded upon in letters such as 1 Corinthians 15. In this chapter, Paul emphasizes the significance of Christ's resurrection as the 'firstfruits' of those who have fallen asleep (1 Corinthians 15:20). He assures believers that just as Christ was raised, so too will they be raised in glorified bodies. This is supported by other passages, including Romans 8:11, where it states that the Spirit of Him who raised Jesus from the dead dwells in the believers, guaranteeing their future resurrection. Thus, the resurrection is central to the Christian faith, providing both a past historical foundation and a future hope.
