Didn't read it but I did watch this well put together video about A History of God.
3.3.3 Atheism: A History of God (Part 1) - YouTube
Very good video, I agree, but ... he did quit reading the book partway through. The point Armstrong tries to make is that "God" could be the intellectual deity apprehended by the philosophers or the the emotionally manifested deity of the evangelicals, or again, the unknowable ground of being experienced by the mystics. These don't exclude one another. One size fits all, because it is adjustable. It can be restyled to taste. We only run into trouble when some people say everyone must believe the same. It is generally the fanatics and simpletons who think there is only one way to see things.
We may start off by reading simple stories in the first grade, and those are appropriate to first graders, but by the time we get to college we have, it is to be hoped but not expected, outgrown those stories. Just so, as children we are shown a simple "God" but as we grow older and have varied experiences our concept of what "God" is will change too. If it doesn't we are stuck with the theological equivalent of "Dick and Jane" and "Goldilocks". (I hold mathematics to be the only reasonable language of theology.)
But even if we eliminate the word "God" from our thinking, because it makes us (or our peers) uncomfortable, we fill that gap with other concepts, perhaps more profound than the incoherent mish-mash that is the "God" of the Bible. Judaism, Christianity, and Islam, all contain many viewpoints and like the blind men and the elephant they all may be partly right and partly wrong, and certainly incomplete. But the elephant is real, even if it is poorly understood and innately incomprehensible.
Richard Feynman said that anyone who thinks that they understand quantum mechanics doesn't understand quantum mechanics. In the same way, anyone who claims to understand God, doesn't understand God. Reality is a tough teacher. The concept of God is a real tool for managing the world, a Swiss Army knife that has many uses, for many different people from morons to geniuses. (Kind of like the Doctor's sonic screwdriver.)
We can, like Einstein, be overawed by reality, and our own ability to comprehend parts of it, just as we may be carried away by music or poetry or dance. It's all part of one thing. We can call it for convenience, God. Our minds like to separate things out, to define things. But we can use many different criteria to set the definitions that divide up the same reality. Some times our definitions overlap, and when we talk among our selves we find that the same words can mean very different things to different people, or even to the same people at different times.
For example we can divide a circle into three parts (a) with two parallel lines, or (b) with with three nonparallel rays radiating from the some point in the circle. The whole set of points that is the circle is covered, but the way we divide it up is quite different. So when person using method (a) names his three parts and the person who uses method (b) adopts those names and they try to have a discussion they fall into confusion and acrimonious disagreement. And we can easily confuse even ourselves if we don't realize that we are really using both methods, or divide our circle with multiply intersecting intersecting complex curves. It would be clearer if I used set theory but some people don't understand even simple math.
I call myself Buddhist, but that does not mean that I am a polytheist, a monotheist, or even an atheist. I am none of those things. I am not separate from any part of what is real. Science tells me that I am a dynamic changing pattern in reality, an electro-magnetic harmony, a puff of dust in the wind, depending on how you look at it, but I am aware of myself, and the world around me. And that, I maintain, is the "image and likeness" of God. (But not God, just an image.)
And as I am, so are you.
I am not offended if you see things differently. I would be surprised if you didn't. That doesn't mean that you can't be absolutely and completely wrong.
