我是从天上降下来生命的粮。人若吃这粮，就必永远活着。

I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.

或者，“你们想立即得到吃的，但是我希望你们看到我就是生命的粮。”

Or, "you want to see bread right now, but I want you to see that I am the living bread."
