How do we know that feeding on Jesus is essential for the Christian life?

Feeding on Jesus is fundamental because He is not only the beginning of the Christian journey but also the source of ongoing life and strength. The metaphor of Jesus as bread signifies that He provides what is necessary for spiritual vitality. His atoning work on the cross secures eternal redemption, meaning He is essential for all aspects of salvation and growth in faith. Thus, believers are encouraged to seek Him daily—His presence and His work—through prayer and meditation on Scripture to find true nourishment.
