"And Jesus answered him, saying, It is written, That man shall not live by bread alone, but by every word of God." - Luke 4:4 KJV
Each Rhema (Strongs G4487) of God... every Rhema of God... not a written code. God had men who were inspired by the Spirit write so that we could have rhemas... living connected thoughts.
That is the way to live today. Bread is wonderful but it is consumed and then it is gone. Rhema is forever. It was and is and is to come.
God... fill us with your Spirit so we can live and think in the realm of rhemas today... redemptive thoughts... things that won't pass away.
