I am the life-giving bread

"I am the life-giving bread which descends from heaven. Whoever eats of this bread will live through all cycles of time. And the bread which I shall give: that is my earthly body which I shall offer up for the life of the world.... Whoever eats my body and drinks my blood has life beyond the cycles of time, and I give him the power of resurrection at the end of time. For my flesh is the true sustenance, and my blood is the true draught. Whoever truly eats my flesh and drinks my blood remains in me and I in him."--John 6:51,54-56
