Best place in this earth to look for everlasting food is in Christ Jesus -the bread of life.
John 6:48-51 (New International Version)
48I am the bread of life. 49Your forefathers ate the manna in the desert, yet they died. 50But here is the bread that comes down from heaven, which a man may eat and not die. 51I am the living bread that came down from heaven. If anyone eats of this bread, he will live forever. This bread is my flesh, which I will give for the life of the world.”
Yes Jesus is the bread of life, the way into heaven. Seek Him and you shall live forever in Heaven!
