How do we know that Christ's sacrifice gives us everlasting life?

The assurance of everlasting life through Christ’s sacrifice is explicitly stated in John 6:51, where He refers to Himself as 'the living bread' and explains that His flesh is given for the life of the world. This emphasizes His role as the sacrificial Lamb whose death and resurrection not only atone for sin but also grant eternal life to all who believe in Him. The perfect obedience and ultimate sacrifice of Jesus fulfill God’s redemptive plan, confirming our hope of resurrection and life everlasting.
