The Gospels – The Gospel According to John
Labour for the food that endureth…
John 6:25-27 When they found him on the other side of the sea, they said to him, “Rabbi, when did you come here?” (26) Jesus answered them, “Truly, truly, I say to you, you seek me, not because you saw signs, but because you ate your fill of the loaves. (27) Do not labor for the food which perishes, but for the food which endures to eternal life, which the Son of man will give to you; for on him has God the Father set his seal.”
Jesus speaks of the Son of Man in the third person which indeed He frequently did. This goes to show that this Son of Man is not Jesus. He said that the Son of Man shall give the meat of life. The Son of Man, the Holy Spirit will give us the eternal meat if we obey Him. The eternal meat is the Word and Power of God that nourishes the spirit. This is the manna for the spirit. Its elixir of life. He went on to say also in the third person that God had placed the seal of approval on the Son of Man. The seal of approval as His Son and to act as His Envoy in all matters in Creation.
