Why do Christians believe in the resurrection?

The resurrection of Jesus is a cornerstone of Christian faith, establishing His identity as the Son of God and the truth of the gospel. Romans 1:4 affirms that Jesus 'was declared with power to be the Son of God by his resurrection from the dead.' The resurrection not only validates Christ's sacrificial death but also provides believers with the assurance of their own resurrection and eternal life. It underscores the victory over sin and death and is essential for the Christian’s hope and assurance in salvation. The resurrection is celebrated as a definitive proof of God's triumph over the grave.
