Jesus explains the true Daily Bread
"Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. For the bread of God is he which cometh down from heaven, and giveth life unto the world."-John 6:32-33 KJV
It's Jesus, and we know him and have him by His Word.
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life."-John 6:63 KJV
