Thank you for your comments. It is good to dialogue with someone who does not deny the reality of spiritual and rational truth.
It seems to me that saying that the physical world is a subset, which seems to make it inferior, of wider rational and spiritual realities is not Biblical. That is a Platonic Greek view. The Bible indicates that Creation took place when God gave order to the material chaos (that God had created.) The fact that God created ex nihilo is perhaps an interpretation of the story, but a justified one.
In no way to I regard these as disjointed sets, but to the contrary, it is the coordination of the three realities that makes God God. God is Trinity and humans are created in the Image of the Trinity (God.)
Humans are physical, rational, and spirit. They are ruled dead when the body is dead. They are dead when the mind is dead, even if the body is alive. They are not considered dead when the spirit is dead, because this can be reversed by the Spirit of God.
The physical, rational, and spiritual are very much related, and indeed all are related that everything is relational.
I don't think that you full understand my position. I do not have a need or desire to partition the spiritual from the physical. Others might, but not me. Indeed above I suggested that the three aspects of physical, rational. and spiritual were similar to the primary colors of light: red, yellow. and blue, which together produce the "color" white or the presence of color when talking about light, and the "color" black or the presence of color when talking about pigment.
The three primary colors are not partitioned, but are a continuum. They are separate because they are different as are the secondary colors.
Let me try this example. A rock is a physical reality, but it is also rational in that it is created by rational natural laws, and spiritual in that it is part of God's plan of salvation. 2 + 2 = 4 is rational, but it is also physical in that it works in the physical world, and spiritual in that it help demonstration the relational nature of Reality. Love (see Paul's definition of love, 1 Cor 13) is spiritual, because it is God's character, which underlies all of Reality, physical, rational, and spiritual.
