First of all, let’s talk a little more about the issue of consciousness being irreducible to non-consciousness. I made the argument that consciousness must be traced back to the First Cause, because you can’t get consciousness from non-conscious stuff. This might have raised a question in your mind: “If consciousness cannot be derived from non-consciousness, then wouldn't it work the other way as well? Wouldn't non-consciousness be irreducible to consciousness? And if this is the case, then wouldn't the First Cause have to have two parts which are irreducible to each other, making him divisible?”
This would indeed be a problem if we were to affirm that consciousness and non-consciousness are completely and ultimately distinct things. But I don't think that is the case. (And in fact it can't be the case, because God must be simple/indivisible!)
Since God is a mind (the Mind), and since God is simple, we must conceive of creation as being produced by the mind of God. In this way, as in many others, God is like an author who writes a novel. How does the novelist produce the novel? She does so by imagining a world—full of events, characters, places, etc.—and thus bringing it into being by her thinking of it. (She will probably then write it down, but it exists in her mind first.) The world of the novel—particularly before the novelist writes it down—is completely dependent for its existence on the novelist and the novelist's sustaining that world in being by her thinking of it. We cannot draw any absolute distinction between the existence of the imaginary world of the novel and the author's perceiving of or keeping in mind that world. To use a phrase from 18th century British philosopher George Berkeley, as far as the world of the novel goes, “to be is to be perceived.”
This is a good analogy for how God creates the world, with a few adjustments: 1. Unlike a human novelist, God can keep the whole universe with all its details—past, present, and future—in his mind at once (and timelessly, since he is outside of time). He has no need to write it down. In fact, “writing it down” is a meaningless concept in this context, for it implies a physical being with space outside of himself and other materials—paper and pen—with which he records his thoughts. God is not in time or space, so there is no place “outside of God” for God to write anything down. Rather than being simply one being in a reality in which he is surrounded by other objects, he himself is the full context of all of reality. 2. A human world-creation is going to lack much reality and substance, because human imagination is very limited and weak. When you create an imaginary character, that character is real to an extent—he really exists in your mind insofar as you imagine him. But he is a mere spectre, a ghost, in comparison to yourself and the rest of the external world. But God's mind is unlimited and full of power. When he “imagines” or perceives a world, that world is full of substance and reality from its overall form down to the smallest details.
So what I'm suggesting is basically what the Apostle Paul said about our relationship with God in the Bible, in Acts 17:27-28: “He is not far from each one of us; for in Him we live and move and have our being.” God created the universe and keeps it in being by his thinking or perceiving of us. This means that material reality is not some thing that exists ultimately independently from mind/consciousness, but is ultimately a part or a mode of consciousness. We should not think of a chair, for example, as a totally independent object made of some substance that is irreducibly distinct from consciousness, but as an object existing ultimately in God's perception and thus as an aspect of that perception. There are not two fundamental substances—consciousness and non-consciousness—but one substance—consciousness—in which is contained the forms and relations of matter.
This makes sense, if you think about it. If you consider the properties of a material object—like a chair—it becomes apparent that they are dependent for their existence on being perceived. What are the properties of a chair? It has texture, color, taste (not a good taste, I presume, but some kind of taste nonetheless), smell, form, dimensions, etc. All of these properties are defined only in relation to perception. Texture is relative to the sense of touch. Color is relative to the sense of sight. Taste is relative to the sense of taste. Smell is relative to the sense of smell. Form and dimension are relative to an observer who is in a particular location. If you think about a chair, you will notice that the different parts of it, which allow it to be an extended object in space, only exist in relation to a grid, the center point of which just happens to be the center point of your own point of view. The dimensionality of the chair is made possible only relatively, in reference to your viewpoint, as you look at the chair from your particular location. This is the case with real chairs, as well as chairs you might imagine in your mind. Look at any picture or piece of art, and likewise you will see that there is always a point of view implied. Form and dimension are inseparable from perception and a perceiver. The very concept of a “material object” makes no sense independent from the concept of the object's being perceived. Matter, by its very nature, is a mode of perception/consciousness. 31
31 I mentioned the philosopher George Berkeley above. While I don't agree with everything in Berkeley's metaphysics, I think he was onto something in his development of his theory of “idealism” (not to be confused with Hegelian or Kantian concepts of “idealism” which are a whole different matter). In his works he tried to articulate and argue for the idea that matter is not fundamentally distinct from consciousness but is an aspect of it. His Treatise Concerning the Principles of Human Knowledge and his Three Dialogues between Hylas and Philonous are a good source for reading more about his ideas on this topic. Jonathan Edwards, the famous Puritan theologian and philosopher, also developed similar ideas.

ADDENDUM 7/4/22: And here is another argument for idealism from the first edition of my book, Why Christianity is True:
First of all, let’s talk a little more about the issue of consciousness being irreducible to non-consciousness. I made the argument that consciousness must be traced back to the First Cause, because you can’t get consciousness from non-conscious stuff. You may have been thinking that I was therefore affirming a kind of dualism, where there are two fundamentally different substances in the universe--non-conscious, or mind-independent, matter (hereafter called MIM for “mind-independent matter“) and consciousness, or mind. And you may have thought, “OK, since consciousness can’t be reduced to non-consciousness, then both MIM and mind must be traced back to the First Cause. But wait! He said before that the First Cause was dimensionless, and hence indivisible. But if the First Cause possesses both a mind-component and a MIM-component, then he would be unavoidably divisible.” If you thought something like this, you are absolutely right. The one flaw in your reasoning is this: I am not actually a dualist. I am an idealist. I do not think that there are two fundamentally different substances in the universe; I think there is only one: mind. I think that all that exists are minds, and that material objects are simply collections of sensory impressions that exist in minds. My desk, for example, is not an object that exists outside of minds, outside of being perceived. It is, fundamentally, a collection of sensory qualities--color, texture, smell, taste, etc.--that exist by virtue of being perceived. The very concept of “sensory qualities” makes no sense unless they are being perceived, or sensed, by a mind.
There are a number of reasons why I think that idealism is true. I’m not going to try to give an exhaustive survey of them here, but I can point out a few: 1. There must be a single, simple, First Cause that is responsible for all the parts of the universe. If this is so, then there can only be one fundamental substance in the universe. What is that substance? It must be either mind, or something other than mind (MIM). It must be mind, because consciousness is something we are directly, immediately aware of. The existence of consciousness is self-evident. Therefore MIM does not exist. Therefore idealism is true. 2. We have no reason whatsoever to believe in MIM. The only thing we actually immediately observe is mind and the sensory qualities that exist in minds. We never observe MIM. Nor can MIM be inferred from what we observe. If MIM exists, it cannot affect mind, because MIM would only be capable of producing MIM-type effects--that is, physical effects (conceived of as something fundamentally different from mental effects). But since mind, in this view, would not be physical, it could not be affected by physical effects. Nor could it, being non-physical, produce physical effects on the MIM. Therefore, the two substances could never interact with each other, meaning that MIM cannot be the cause of our sensory experiences. This means that there is no basis for inferring MIM from what we directly observe (consciousness). We thus have no reason whatsoever to believe in MIM. So I’d rather not believe in it. 3. MIM is not only unobservable and uninferable from what is observed, but the very concept of it is absurd. Let’s focus on the idea of a particular MIM object--say, a chair. According to the MIM theory, the reason we perceive the sensory qualities associated with a chair is because there is a MIM chair, an object existing apart from being perceived and therefore lacking all sensory qualities as they exist in minds, which somehow produces the sensory qualities of a chair in our minds. What is this MIM chair like? Well, we must abstract from it any qualities that only make sense in terms of existing in sensing, perceiving minds. Does the chair have color? Unfortunately, color is a sensory quality that only makes sense in reference to the sense of sight. Does the MIM chair have texture? Unfortunately, texture is something that only makes sense in reference to the sense of touch. Well, does the chair have smell, or taste? No, these are obviously intrinsically connected to the mind’s senses as well. Does the chair have dimension? Does it have width, height, etc.? Well, if you think about it, you can see that dimensional concepts are intrinsically related to perceiving minds as well. The very concept of a dimensional object which has various forms of extension in space implies that that object is being viewed from some particular location. Imagine a chair in your mind. You will notice that the different parts of the chair, which allow the chair to be an extended object in space, only exist in relation to a grid, the center point of which just happens to be the center point of your own point of view. The dimensionality of the chair is made possible only relatively, in reference to your viewpoint, as you look at the chair from your particular location. This is the case with real chairs, as well as chairs you might imagine in your mind. Look at any picture or piece of art, and likewise you will see that there is always a point of view implied. So if we abstract all dependence on a perceiving mind from our MIM chair, we must abstract all color, texture, sound, smell, taste, and dimension. What is left? Nothing. The concept of a “chair,” or any other physical object, simply has no meaning apart from the concept of sensory qualities which can exist only in minds. 1
One objection that might be raised against idealism is that it is obvious that our individual minds are not independently producing the world we see around us. There are two problems with supposing this to be the case: 1. I would have to be a far greater mind than I know myself to be to be responsible for the existence of the entire universe. My imagination is extremely limited. There is no way the person that I call Mark Hausam is keeping the whole universe going coherently, with all its detail, by the power of my own imagination. 2. Reality clearly extends beyond the limits of my knowledge. This is evident because I find myself constantly learning new things, which makes no sense if my mind is the source of all reality. Also, assuming the other people in the universe are real, independent minds as well, as they appear to be, how are we all experiencing the same shared reality if we are all independently making up the world? So clearly there is a real world external to our individual minds that we are participating in. How can idealism deal with that? Don’t we need MIM to account for it? Well, bringing in a concept that is logically absurd won’t help, even if it is the only thing we can think of. But we don’t need it anyway, because idealists have another perfectly valid explanation for these facts. We would suggest that the universe is ultimately not in my mind or in your mind, but in God’s mind. The omniscient First Cause is upholding all things in his mind, and we are merely participating in someone else’s creation ultimately.
Another objection that might have occurred to some of you when I was talking earlier about consciousness not being reducible to non-conscious stuff is that it is obvious that consciousness is interwoven with physical reality. My mind is clearly connected to my brain. If you affect my brain, you can affect my mind. Remember Phineas Gage, the railroad engineer who had a metal spike fly through his head, taking out part of his brain? He lived, but afterwards his personality was different. He had been a mild, civil person; but afterwards, he was rude and vulgar. His personality had been affected by the change to his brain. So how can I say that consciousness is simply different from physical stuff? How can I say that mind can’t reduce to the physical brain? Well, I think I have already answered that question by telling you that I am an idealist rather than a dualist. For a dualist, I think these objections are insurmountable. But, as an idealist, I do not make a distinction between mind and brain. I would say that my brain is simply the physical manifestation of my mind. I am in a particular location, I see things from a particular point of view. My mind is located, right now, in an apartment in Salt Lake City, UT. So if you look towards the spot from which my point of view arises, you will see this human-shaped object sitting at a computer, typing on the keyboard. If you look inside my head, you will see this complex mass of matter that is my brain. Is that brain me? Yes, I think it is. My brain is how my mind manifests itself in a three-dimensional experiential world. Minds manifesting themselves in this way makes it possible for minds to interact with each other in our three-dimensional universe. So if something happens to my brain, it happens to me. I have no problem with this, because I am not a dualist who has to say that my brain and my mind are fundamentally different substances, irreducible to each other in an absolute sense. 2
At any rate, there must be a single, simple First Cause that is the source of all things. Therefore, there can only be one fundamental substance in the universe, and that substance is mind or consciousness.
1. Someone might suggest that color, for example, can indeed exist outside of perceiving minds. The experience of color cannot, but the wavelengths of light that cause the experience of color can. But what is light? Well, that is a big question; but whatever light is, insofar as it can be detected by our senses, it is a part of the matter-energy world and only exists by partaking in sensory-bound characteristics like dimension, location, etc. In other words, the same reasons that lead us to think that the concept of “chair” has no meaning apart from the sensory qualities, existing in minds, that make up the concept, also lead us by the same reasoning to think that the concept of “light” has no meaning outside of being perceived by minds. This reasoning applies equally to all matter-energy objects which are detected by means of the senses.
2. I am not here getting into the concept of life after death. I do think, for biblical reasons, that life continues in some form apart from the body after death. This is clearly a change from how life occurs while I am alive in this world, but I see no logical problems with the concept. I don’t see any compelling reason to think that life cannot continue in some other form after death. But I don’t think the idea of life after death has to imply that my brain is not the manifestation of my mind at least in this life.
