How do we know Jesus is the bread of life?

Jesus identifies Himself as the 'bread of life' in John 6:35, indicating that just as physical bread sustains us, He provides spiritual sustenance essential for eternal life. This metaphor emphasizes the necessity of faith in Christ for true fulfillment and life. By partaking in His body and blood, believers are nourished spiritually and given the privilege of fellowship with God. This point underscores the richness of grace that believers experience in communion, where they receive more than mere sustenance but a deep, abiding relationship with Christ.
