THREE = 1 and ONE Equals 3
Something that has puzzled me is the Nature of God - I do not mean the ideas presented in the Bible about his character, he is indeed good and that is easy to understand, but his "physical" nature (and I use the term "physical" VERY loosely, since God is of the Spirit not the physical). The most puzzling part about God is how the three God heads can act separately but still exist as one being. Now this idea has never presented a problem when it comes to my personal belief, I just took the leap of faith, but it does often come up in argument between Christians and Muslims and I am sure it has tested the beliefs of Christians during the past.
What I present next is an attempt at an explanation of this conundrum. It is not nessacerly the right answer, but its the one I believe. Also it is not a complete answer either, its as much as a finite being (man) can grasp about the infinite being (God). Neither is it anything exceptionally original I have thought up, but a collection of Christian ideas dating back years/centuries.
We are three dimensional beings. For instance, in space, you can move up, down, left, right or some compromise between these directions. We have depth. If humanity was one dimensional then he could only draw a straight line, because that is all that the one dimension is made up of. If he were two dimensional then he would be able to draw figures, like squares and triangles. These are figures made up of lines (one dimension). In the third dimension you can build solid bodies like cubes, but cubes are made up of 6 squares which are two dimensional.
It is simple. A one dimensional world is made of lines. In the second dimension the lines come together to make a figure. Finally, in the third dimension, you still get figures but three put together to make a solid body. Now, what is happening is as you go from one level to the next more complicated level, you do not leave behind the simpler level. But the simpler levels are combined in such ways as to be (nearly) beyond the imagination of a being operating on a simpler level.
Now we come to God. Christianity explains that mans dimension (the third) is simple compared to Gods, which is the divine. On the human level one person is one being, and two people are two separate beings - just as in two dimensions, one square is one figure and two square are two separate figures.
On the divine level you still have personalities, and beings who operate independently, as on the human level, but in the divine, they combine in such ways, that we who are not on the level, can not fully understand but can only glimpse. Just as a being on the second dimension could hazard to guess what it a cube may be like, but can not actually do it. He can only get a faint notion.
The same applies to man when he imagines God. On the divine level you have a being who is three persons but remains one being, just as a cube is six squares while remaining one cube.
When we think this way we begin to get an idea of a super-personal being - something more than a person. Then, once we have been told we probably feel a little foolish, because its something we ought to have guessed because it fits in so well with the way we know things already operate.
