Literary History of John 6:25-69:
The apostle John was an eyewitness to the life and teachings
of Jesus. He was one of the Twelve. He was also the last of the
Apostles to write and to die. He refers to himself as the
"disciple whom Jesus loved."
Following the details of the multiplication of the loaves and
fishes--biographical, Jesus walking on the sea--biographical,
Jesus reacts to the crowds' need for signs. Jesus takes them
from manna, bread from heaven, to "true bread from heaven
(v. 32)" ... "I am the bread (v. 35)." "I am the bread that came
down from heaven (v. 41)." This is God saying this: "I am the
bread that came down from heaven." If He was not really the
bread that came down from heaven, His omnipotent and creative
Word would then have made it so.
