"It is written: 'Man shall not live on bread alone, but on every word that comes from the mouth of God.'" (Matthew 4:4)

Here Jesus is responding during his 40-day fast, after:

The tempter came to him and said, "If you are the Son of God, tell these stones to become bread." (Matt. 4:3)

The "tempter" was referring to the fact that Jesus was hungry and all around him in the desert were stones.

So what is Jesus speaking of as he quotes this passage from Deuteronomy?

Here is the passage Jesus is quoting from, spoken by Moses to his followers after they had traveled through the desert:

"He [the Lord your God] humbled you, causing you to hunger and then feeding you with manna, which neither you nor your ancestors had known, to teach you that man does not live on bread alone but on every word that comes from the mouth of the LORD." (Deut. 8:3)

What does this passage mean and what does Moses and Jesus mean by "man does not live on bread alone but on every word that comes from the mouth of the LORD" ?

"'Man shall not live on bread alone..."

Moses and Jesus were speaking of our identity and our natural position. We are not these physical bodies. These physical bodies are merely temporary vehicles. They will last no more than a few decades and then they will die and begin to decompose - eventually turning into dirt.

Our true selves are the spirit-persons living within these physical bodies.

We can see this when we look at a photo of our body when it was a child. That body is now gone. Every molecule that made up that body has been replaced by new molecules - as every molecule in the body is replaced within five years.

Who is looking at the photo? And who was there when the photo was taken? Don't we say "this is me"? If the childhood body is gone now, yet we still say "this is me" - this means that we - "me" - is not the physical body. We are the personality who pervaded - who existed - within both the child body and the body we wear now.

This spirit-person is invisible to the physical eyes, because these eyes cannot see into the spiritual dimension. The spirit-person is of another plane of existence. It is of the spiritual dimension - a dimension not seen by the physical eyes. The physical eyes were designed to see a particular range or spectrum of wavelengths and not others. They see certain frequencies of lightwaves as those lightwaves bounce off of the molecules of the forms of the physical world.

This is why we cannot see any difference between a living body and a body that just died. We don't see the spirit-person leaving the physical body.

This is what Jesus and Moses meant by "man shall not live on bread alone." Because our identity is spiritual, we require food that is more than physical "bread." The physical body may need constant fuel in the form of "bread" in order to remain functioning. But the spirit-person that Jesus and Moses are speaking of needs something more. What is it?

It is spiritual food. It is the food that feeds the spiritual self. And what is this spiritual fuel?

Our relationship with the Supreme Being. This is what gives each of us real life. And this is the only thing that will make us happy.

Just think about it. We are each looking for happiness in this physical world and never finding it. We look for happiness in the objects of the senses. We look for happiness by achieving wealth. We look for happiness by achieving fame and the acclaim of others. We look for happiness by having a big house. We look for happiness by achieving some goal of accomplishment.

Yet none of these physical things make us happy. We are still empty within. Even those who have the most of these things are still empty within.

So we look for happiness through our relationships with those around us. We look for happiness in our spouses, our children and our family. And to a degree, we do find a glimpse of happiness within these relationships.

But this fleeting happiness fades as these people leave us or break up with us. Our spouse may divorce us or die. Our children will grow up and move out. Our mother and father and grandparents will all die one day. Each of these events will leave us empty and alone.

Because they are temporary relationships. Yes, we might see them in a different lifetime but we won't recognize them as we knew them before. We will have to start a brand new relationship with them and won't remember the last one we had with them.

In other words, all the relationships of the physical world - these relationships of the physical body - are all temporary. They don't last.

But this is not the case in the spiritual realm. The Supreme Being is eternal and our relationship with the Supreme Being is eternal.

We have forgotten this relationship with the Supreme Being. This is the purpose of the physical world and these physical bodies. To help us escape from and forget the Supreme Being.

But our relationship with Him is forever. We simply have forgotten that relationship.

This is because the Supreme Being gives each of us the freedom to love Him or not. Love requires freedom.

So those of us in the physical world are here because we chose not to love the Supreme Being.

Even so, the Supreme Being wants us to come home to Him. He wants us to return to our loving relationship with Him. This is because He loves us and He knows we will only be happy when we have resumed our relationship with Him.

And what is that relationship? It is the loving relationship we are perpetually looking for as we seek love within the physical world. This is the loving relationship we seek as we look for our soul mate and seek love with family members. We are looking for our lost relationship of love with the Perfect Person.

"...but on every word that comes from the mouth of God.'"

"Living on every word that comes from the mouth of God" means living for the Supreme Being - dedicating ones life to the Supreme Being.

Just think of what we do when we are in love with another person. When the other person says they want to go to the fair, what do we do? We take them to the fair. When they say they want to eat a certain food, what do we do? We go get them that food. When they say they want to play golf, what do we do? We go play golf with them.

What are we doing as we are doing all those things? We are living off of "every word that comes from the mouth" of that person.

Yes, "every word that comes from the mouth" is an expression. It is an expression - used by Moses and even still used today - that refers to doing what is pleasing to that person. It refers to having a loving service relationship with that person.

And this is what Moses and Jesus were asking of their followers: To renew their loving service relationship with the Supreme Being.

And Jesus' lived this instruction as well. Consider this statement he made:

"By myself I can do nothing; I judge only as I hear, and my judgment is just, for I seek not to please myself but Him who sent me." (John 5:30)

Jesus is stating that his pleasure ("I seek") is derived from pleasing the Supreme Being. He also states this elsewhere - for example:

"For I have come down from heaven not to do my will but to do the will of Him who sent me." (John 6:38)

What is Jesus referring to? He is referring to his relationship with the Supreme Being. He is speaking of his love for the Supreme Being and he wants to do whatever the Supreme Being wants him to do. He is, in fact living off of "every word that comes from the mouth of God.'"

And because the Supreme Being wants each of us to return to our loving relationship with Him, Jesus' efforts were focused upon encouraging and teaching those around him to return to their loving service relationship with the Supreme Being. This was also clearly communicated in the most important teaching of both Jesus and Moses:

" 'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment." (Matt. 22:37-38)
