How do we know Jesus Christ offers salvation from death?

The foundation of salvation from death is rooted in the redemptive work of Jesus Christ. John 3:16 articulates the essence of this salvation: 'For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life.' This promise indicates that through faith in Christ's sacrificial death and victorious resurrection, believers receive not only forgiveness for their sins but also the gift of eternal life. The Apostle Paul speaks of this in Romans 6:23, identifying that 'the free gift of God is eternal life in Christ Jesus our Lord.' Therefore, it is through Christ that believers gain victory over death and the judgment it entails.
