This first temptation is about intense hunger and need. The devil now comes with seemingly reasonable temptation.
The story seems trivial, and temptation is often the same. Frequently we are tempted to what is not obviously evil, but nevertheless compromises us. Small as this seems, it would have been a terrible departure from the will of God, and a breach between himself and the Father. Sometimes massive temptations come in small guise: to have this extra possession, to listen to this music. It is a deadly compromise, a massive concession.
For us, Satan makes the temptation work both ways: ‘If you are truly a child of God, do this, do that; take your ease; look after yourself.’ We are pushed one way, to doubt our salvation, but then we are pushed the other way, to act presumptuously.
Is Satan a real being or just a metaphor for evil within? Does temptation come entirely from within or are we tempted by a being who is external to us who has real existence? In the case of fallen human beings, the answer is that we are tempted both from within and without, but Christ had no sinful nature. He was made only in the likeness of sinful flesh (Romans 8:3). The temptation of Jesus Christ can only be explained in terms of a real devil coming to him and making suggestions from outside of him.
