Believing in the bodily resurrection of Jesus is the foundation of Christianity because it confirms that Jesus is who He claimed to be—the risen Lord and Savior. Without it, our faith would be futile, and we would still be in our sins (1 Corinthians 15:17). The resurrection demonstrates God’s power over death and affirms that our hope for life after death is real. It also validates the promise of eternal life for believers, ensuring that physical death is not the end but a transition to everlasting life with God.
