How do we know the resurrection of the body is true?

The truth of the resurrection is grounded in the resurrection of Jesus Christ, which is documented in 1 Corinthians 15 and supported by eyewitness accounts. Over 500 individuals witnessed the risen Christ, including the apostles and Paul, who experienced a radical transformation after encountering the risen Lord. The resurrection is essential to the gospel, as it assures believers that just as Christ was raised, they too will be raised in glorified bodies at the last day. This hope is a cornerstone of Christian faith, as it underlines the complete work of salvation and the power of God to grant eternal life.
