Zero is certainly illusive and "not seen". Is zero eternal? If all that has substance i.e. wealth and things we accumulate in life are, as the saying goes, "you can't take it with you." Then how can something that is nothing be eternal? How can nothing be eternal? Is zero felt? We can feel things we see and even things we cannot see. Even acts of love can be seen. Much of what we feel that we cannot see is fantasy. If it was truth then there would not be such conflicting accounts of this invisible world that religion seems to have a monopoly on.
Science concerns itself mostly with what is seen yet it also stipulates that matter is neither created or destroyed? Does this not conflict with the bible? Is can matter be unseen? Is zero another form or matter? Light being both a wave and a particle is it the particle that is seen and the wave that is unseen? IS the wave eternal and the particle temporal? If light is both wave and particle and light is seen then how can god be light? God speaks light into being...
As Paul the apostle on the road to Damascus saw a blinding light that claimed to be Jesus, is Jesus not seen? Jesus being seen of many would imply that he is temporal? Or is it the spirit within Jesus that was eternal just as it is the wave within the particle that may hold the key to eternity. Yet after Jesus descended into hell and freed angels from the abyss he returned and appeared in a new dynamic body and was "seen"... Yet he forbade Mary at the grave to touch him For he has not yet ascended (whatever that means). It seems that again ambiguity of what is seen, felt, heard, smelled, tasted or perceived as flesh are just as eternal in their own way as spirit. It is called the circle of life. Just as spirit requires knowledge to become holy a body requires spirit to become eternal. The eternal is dependant upon the temporal to exist (or in this case to not exist).
God made man/woman in his own image. And if god has an image... would that not make God seen and temporal? If this image is spirit would that also make the spirit seen and temporal?
God is pure ambiguity (and yes, that is an oxymoron).
