There was once this town that had a person known as the firefighter and any time a fire would break out they would gather and plead to this person to put the fire out because to them it was beyond their knowledge. This person being compassionate and having a great love for these people would take this great machine and go to the fire. When they got to the fire they would take what they called a hose out of this great machine and bring it near the flames, this great machine also carried much water and the firefighter using the hose and the water would put the fire out. And the people of the city would gather and rejoice thanking the firefighter for the miracle of putting the fire out. But the firefighter would say to the people I did not put the fire out it is the water that put the fire out all I did was guide the hose, for without the hose the water could not reach the flames. All I possess is the understanding of water and the knowledge of where to guide the hose. As always the townspeople would listen intently and nod their heads to the wisdom the firefighter was giving them, then they would praise and thank the firefighter again for the miracle of putting out the fire and be about their business until the next time.
So it is with jesus's healings. Jesus said himself it is not me, it is my father that does the work. Jesus knew he was dealing with concrete reality and not magic or miracles. Jesus's oneness with all of creation His understanding of how the universe truly works gave him the knowledge, power and focus to manipulate and let this infinite energy that permeates and flows through all of creation to manifest through him. For Jesus it was no different to perform these so-called miracles than to breathe.
For me I do not believe in miracles or magic. For me I believe that science one day if they expand their concept of energy and force to include thoughts, emotions and evolution not just at the atomic level but at the quantum and subatomic level and understand that we are mentally, spiritually (1) and physically entangled with all of creation, only then will we expand our understanding of reality and existence. Only then will we be able to manifest as Jesus did. The evolution from quantum states to the subatomic to the molecular, manifesting in our physical existence is how all of existence manifested regardless of how many dimensions or universes there are.
And as all analogies or parables go there are no true separate parts it's all just one.
(1) spiritually: I believe that our consciousness, our thoughts, our knowledge, the wholeness of what we are beyond the physical, our ability to truly create is a form of energy in and of itself, a coalescence and manifestation of a unique form of energy that dose not require a classical physical form for existence but only for parts of it's evolution. i.e. Our Soul.
