The Eucharist is the food that feeds my spirit; “flesh profiteth nothing”.
God's word is what feeds my spirit.

Matthew 4:4 But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
John 17:7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
