Jesus is identified in the waters of baptism as the Son of God, and immediately the testing begins. After a 40 day and 40 night fast, the Scripture says Jesus was hungry. At that point of weakness, here comes the always present, prowling adversary, the devil, drawn like a moth to the light. You can do it. You can feed yourself AND prove to the world that you are the expected prophet like Moses.
Some people believe that way.
Now, note what Jesus did NOT do in response to that temptation. This is where His example can help us. That would be straw making a pact with fire, giving the tempter a foothold. I DON'T think the point for us is simply that we should memorize Scripture and throw it into the face of temptation whenever it arises, like some spiritual aspirin tablet. God is able to supply the physical needs of my body whether I eat or not.
