In Luke, we find Jesus facing off with satan. Satan was on a mission to tempt Jesus. After 40 days in the wilderness without food or water, satan figured that he had the perfect thing to tempt Jesus with -- hunger.
So, satan taunts, "If You be the Son of God, change these stones into bread." I can just imagine Jesus calm turning to satan and saying in a very even voice, "Man does not live by bread alone, but by every word that proceeds out of the mouth of God!"
Can you just imagine how that must have burned satan up? He tried and he tried, but he just couldn't.
Each and every day I am more and more convinced that those words that Jesus spoke in the dessert are more than true. They are vital. I can skip a meal. I can even survive without a day's meal, but if I skip a day of reading my Bible, I really become spiritually malnourished.
When temptations come, I want to be able to say no and drive satan crazy too. Or as my Mammaw used to say, "Give the devil a black eye!"
