How do we know the doctrine of the bread of life is true?

The doctrine is firmly rooted in Jesus' own words in John 6, where He asserts that He is the living bread that came down from heaven. This claim is not just a metaphor; it carries profound theological implications, identifying Jesus as the fulfillment of God's promise for salvation. The historical context, along with the fulfillment of Old Testament prophecies concerning the Messiah, further confirms this truth. Additionally, the transformative experiences of believers who have partaken of Christ by faith provide personal testimony to the doctrine's validity.
