Lately I have been thinking on the nature of the Triune God, in the sense of what is God. The bible goes to great length to describe the character of God, and the power of God. However, it doesn’t spend too much time expounding as to what He is exactly, other than the fact He seems to be made up of more than one individual.
Over the centuries many people have tried to make sense of the unity as well as the individuality of God as three beings who equate to one entity. This is my attempt to decipher this seemingly paradoxical reality based on my current knowledge and understanding.
I believe this conundrum comes from not considering the plane of reference of the observer. Taking simple human examples, this is an image of a cube (albeit it’s a 2 dimensional representation of which our brains can transpose into a 3 dimensional reality). 
Our brain can discern what it is when looking at it from 3 dimensional space i.e. it has a height, width and depth dimension. Assuming for a moment that somebody lives in a 2 dimensional world called Flat Land. Imagine now the cube passes through flatland, in different orientations, as can be seen in the following examples:
From the reference view of the people of Flat Land, it will appear that the shapes are distinct form one another with no overlap. However, in the cube dimension, there is a real spatial relationship that exists between the shapes but cannot be perceived from Flat Land. They are both individual shapes from the reference view of Flat Land, but in reality, it’s one shape from the reference view of the cube.
Another example is that if you are to take a snapshot of a movie at the beginning and another snapshot at the end. Without any context, those two images will seem completely unrelated to each other and the reality of each will be 2 individual images. However, if we add the time dimension and allow the movie to progress, then we can see the relationship between the beginning snapshot and all the other snapshots leading to the closing image.
In a similar way, one can think of God as a complex higher dimensional being who based on our reference plane seems like three individual beings. In reality if we are to look at Him from the reference plane of the God dimension, He is truly one being with a higher dimensional relationship between Himself. This relationship has been thought to be the love that binds the three person of the Godhead together. However, I believe in addition to love they have for each other, there is a very real reality connection (I don’t want to call it energy or matter, as those are concepts that belong in this reference plane). Thus God is truly one being but to our eyes He doesn’t seem so. The only way we can know His reality is to either go to where He exists which is impossible, or for Him to tell us what He is really like which He has done through the bible. We can either choose to believe Him or not, the choice is ours, but that doesn’t change what the nature of what reality is really like.
