“See that you do not look down on one of these little ones."Jesus is speaking of humility here. This is one of the primary requirements for entering the spiritual realm. In the physical world everyone is proud of themselves. The inhabitants of the physical world are seeking to be higher than others. We are seeking to be better than others. This is why so many strive to win sporting contests and various other competitions. We want to be the hero. We want to be the greatest. We want to be the victor.
In the spiritual realm, the Supreme Being is the hero. He is the greatest. He is the victor. And this is His natural position, because in fact, He is these things. He doesn't have to prove it to anyone.
The inhabitants of the spiritual realm thus do not struggle to win anything. They are the fans of the Supreme Being. They recognize and support the Supreme Being's superiority. They are feeling humble about their own positions. They see themselves as insignificant and see the Supreme Being as their personal hero.
As such, the inhabitants of the spiritual realm also see others as greater than themselves. This is because they are satisfied within. They do not need to promote themselves or gain the attention of others because their relationship with the Supreme Being completely satisfies them.
In the physical world, because we have forgotten our relationship with the Supreme Being we feel empty inside. Our forgetfulness of our relationship with God has created a hole within us.
In an attempt to fill that hole, we seek the love and attention of others. This means we strive to achieve fame and recognition, and this is achieved by winning or otherwise becoming accepted - which drives many to join groups or organizations in order to be accepted by others.
But we quickly find that accomplishing the acceptance or recognition from others does not satisfy us. This is found by sportsmen who achieve some big success - say an Olympic athlete who wins a bunch of gold medals. Once the athlete gets the gold medals and receives the fame and recognition for their accomplishment he begins to understand that it brings no real fulfillment. It does not fill that empty hole within.
This is also found out in so many other ways. For example, a family man or woman will feel that having a child will fill that hole within but they soon find out that the child is a responsibility and a lot of work - and the hole still remains. For this reason, they might think that another child will do the trick. Or maybe having an affair. Or maybe something else.
As each of us seeks and gains the various accomplishments the physical world offers us we continue to find this emptiness continues even though we become winners or gain the recognition of others.
This is because the emptiness is only filled by regaining our lost relationship with the Supreme Being.
Each of us has one or multiple guardian angels as we take our physical journey. These angels watch us and care for us. They hope the best for us. They support the process of learning that the physical world takes us through. They typically do not interfere, but they try to encourage us to make the right decisions.
This interaction takes place because we are missed in the spiritual world. We once dwelled in the spiritual world. In the spiritual world, no one is forgotten, and love and care pervades. Those we left in the spiritual world - especially the Supreme Being - have not forgotten us. They want us to come home.
Consider the fact that prior to our fall from the spiritual world (due to our becoming self-centered) we were not only relating with the Supreme Being, but we had many variegated relationships with the other children of God. The spiritual world is full of individuals just as this world is. The only difference is that in this physical world, mostly everyone is selfishly motivated, whereas in the spiritual dimension, everyone is loving the Supreme Being and motivated by their care for others.
This opposes the concept of heaven as portrayed by many over the centuries, of God being a vague impersonal force or floating apparition. By the phrase, ".... always see the face of my Father in heaven.” we can know that the Supreme Being is a Person. And we can know that He is personally present in the spiritual realm - and the inhabitants of the spiritual realm have close personal relationships with Him.
With regard to the guardian angels watching over us, it is important to understand that we are not these physical bodies. We are each a spirit-person who is currently operating a temporary physical body.
We might compare this to a person who sits down in a car and drives a car away. The car is not the person, but is the vehicle for the person. When the car stops, the person gets out, just as when the body dies, we leave the body.
We might better compare it to a person who sits down at a computer to operate a video game. The person will pick an icon and the computer game will take the person away into the game - even though the person is still just sitting at a computer. In the same way, while the spirit-person is operating a physical body, from a spiritual aspect the person is not necessarily away from the spiritual realm - we still retain our spirit-person form - but it is covered up. Our consciousness is preoccupied with our false identity and the illusions of the physical realm.
Within the physical world we are enamored by space and time. We look through the molecular arrangements called our eyes and see light bouncing off of other molecules and we surmise that we are seeing reality. What we are actually seeing is molecules swirling around us, taking on shape and form momentarily and then moving on. Every "thing" we see is recycling molecules. Even our body recycles molecules. Scientists have found that within five years every molecule in our body will be exchanged for another - rendering a different body.
It is like looking at a waterfall. Because the water within the waterfall is always moving, we are never seeing the same waterfall. The water is always new water. This is how molecules are also moving around us - never standing still. Always in motion.
So our concept of time and space is illusory. The reference points we make are all in motion so there is no standard of reference that we can consider constant in the physical world.
The only things that are constant are the spiritual elements existing within this physical world. The personality that is "me" is constant. The Supreme Being is constant. The spiritual realm is constant.
We might compare the physical world to a movie set. The movie set is built up specifically to make a film. The set is not a real place where real people live. It is a facade of a real place. It is set up to give the movie goer the impression that the place in the film is real.
In the same way, the physical world is not a permanent place for the spirit-person to reside. It is a temporary place set up to enable us to act out our self-centeredness. To hopefully learn that we aren't going to become fulfilled by winning or by becoming better than others.
The only thing that will fulfill us is our relationship with the Supreme Being. This is a subordinate position. We are the Supreme Being's subordinates. Yes, the Supreme Being gives us a chance to play out our self-centeredness in an attempt to try to be the center of it all. But this is because He gives us the freedom to love Him or not. Because love requires freedom.
And as Jesus states here, love also requires humility.
