Why is the concept of Christ's resurrection important for Christians?

The resurrection of Christ is foundational to Christian faith as it signifies his triumph over sin and death. According to Isaiah 53:10-11, it is prophesied that Jesus shall see his seed and prolong his days, which is fulfilled in His resurrection. This event assures believers of the reality of their own resurrection and everlasting life. As Paul states in Romans 4:25, 'He was delivered up for our trespasses and raised for our justification.' Thus, Christ's resurrection not only confirms the effectiveness of his atoning work but also provides believers with the assurance that they too will rise, highlighting the hope of redemption and eternal communion with God.
