How do we know death is not the end for Christians?

For Christians, death is not the ultimate conclusion but a transition to eternal life. This belief stems from the resurrection of Jesus Christ, which is foundational to Christian faith. As stated in 1 Corinthians 15:55-57, death has been swallowed up in victory through Christ, assuring believers that they will also be raised to new life. The resurrection transforms death from a fearsome end into a temporary sleep, providing immense hope and assurance for those who trust in Christ. This hope is not based on wishful thinking but is grounded in the historical reality of Jesus' victory over the grave, signifying that believers too will experience resurrection and eternal communion with God.
