True Food, True Drink, and Union with Christ – John 6:53–59


Listen Later

In this episode, we stay in John 6 and walk through Jesus’ shocking words about eating His flesh and drinking His blood. Far from softening His message to keep the crowd, Jesus intensifies it—pressing hard on their unbelief, their fixation on physical needs, and their confidence in external religion.

We look at the four promises Jesus makes to those who “feed” on Him, clarify why this passage is not teaching Roman Catholic views of the Eucharist, and see how manna in the wilderness points to Christ as the true bread from heaven. From there, we move into the rich doctrine of union with Christ—Christ in us and we in Him—and think through how that reality should affect our view of sin, suffering, the future, and the chaos of our current world.

Key Topics Covered

  • Jesus’ hard saying: “Unless you eat the flesh of the Son of Man and drink His blood, you have no life in you”

  • Why Jesus doesn’t dilute His message to keep people comfortable

  • James Montgomery Boice on doctrine that leads to true peace vs. peace at the expense of doctrine

  • Four promises tied to eating His flesh and drinking His blood:

    1. Without Christ, there is no life

    2. With Christ, there is eternal life and a promise of resurrection

    3. His flesh is true food and His blood true drink

    4. Those who feed on Him abide in Him and He in them (union with Christ)

    5. Why John 6 is not about the Lord’s Supper granting salvation

    6. Manna vs. Christ: temporary provision that ends in death vs. true bread that gives eternal life

              • Our flesh is never satisfied; Christ alone is true food and true drink.

              • “You can read the Bible all day, but if you don’t absorb it, you won’t be changed.”

              • Union with Christ means Christ in us, we in Him, and our lives re-centered around Him.

              • We should be broken over our sin and yet deeply comforted that Christ’s blood truly covers it.

              • We mourn the state of the world but do not live in panic—God wins, and Christ holds His people fast.

                Big Takeaways
                1. No Neutrality with Christ

                  Jesus doesn’t leave room for half-hearted, external religion: if we do not truly partake of Him—trusting, feeding on, and embracing Him by faith—we have no life.

                2. Union With Christ Changes Everything

                  Being in Christ and Christ in us reshapes how we see our sin, our trials, the future, politics, and the decay of culture. We test ourselves not by feelings, but by what our lives revolve around.

                3. Peace Flows From Sound Doctrine, Not From Softened Edges

                  Real, lasting peace comes from the hard but glorious truths of the gospel—God’s sovereignty, Christ’s sufficiency, and the believer’s secure union with Him.
