The answers in the verse . The full verse .
Christ wasn't speaking in parable.
It's a matter of fact statement .
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.
Christ is quoting Deuteronomy :
He is directing Christians to learn all of Gods words.That includes the OT.
Deuteronomy 8:3 And he humbled thee, and suffered thee to hunger,
and fed thee with manna, which thou knewest not, neither did thy fathers know;
that he might make thee know that man doth not live by bread only, but by every
word that proceedeth out of the mouth of the LORD doth man live.
You know Christ is concerned with the life or death of the soul .
All the words of God, build the spirit and soul. It brings about righteous acts in a true believer
weaving fine linen they wear in heaven .
Christ was accused of the scribe and pharasess of not fallowing their traditions about washing hands..
The the explanation of this parable.
Matthew 15:11 Not that which goeth into the mouth defileth a man;
but that which cometh out of the mouth, this defileth a man.
Matthew 15:18 But those things which proceed out of the mouth come forth from the heart; and they defile the man.
Matthew 15:19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:
20 These are the things which defile a man: but to eat with unwashen hands defileth not a man.
If what comes out is the words of God, that brings life.
Christ is the living water for example .
without water you die .
Without Gods words, which also foretell of Christ, you will die in your sins .
It was one of the main warnings
if what comes out is of self, and confusion of the world, that beings death.
