How do we know that Jesus Christ is alive?

The resurrection of Jesus is foundational to the Christian faith, as articulated in 1 Corinthians 15, where Paul states that Christ died for our sins, was buried, and rose again on the third day, appearing to many, including the apostles. These eyewitness accounts validate the truth of the resurrection, which is not only a historical event but also a divine affirmation that Christ has triumphed over sin and death. This living faith brings hope to believers, reassuring them of eternal life and the promise of seeing Christ, as articulated in the assurance of Job that 'my Redeemer lives' (Job 19:25).
