After fasting forty days and forty nights, he was hungry.  The tempter came to him and said, “If you are the Son of God tell these stones to become bread.”  Jesus answered, “It is written: Man does not live on bread alone, but on every word that comes from the mouth of God.”

The Creator and sustainer of all things certainly has the power to re-create that which He has made – stones to bread, rocks into children of Abraham(Chapter 3:9)  Even though he is hungry, food is not the important thing at this time. Exhibiting his power is not the important thing.  Instead, He shines the light on the importance of knowing God’s Word, and keeping it,  even in times of temptation,.
