Hi Ken, I hope to take the first-rate mystery out of the Trinity.
Years ago when I honestly looked at this question, this is what I found.
It was said that the doctrine of the Trinity teaches that there is one God, yet three distinct persons, each person is the same in substance and equal in and power and glory .
I had discovered an interesting verse in the bible that helped me understand the trinity question more clearly. Hope this will help you.
In Roman 1:20 it says, (I have included verse 19 to show its context)
19: Because that which may be known of God is manifest in them; for God hath shewed it unto them. 20: For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
Basically this is saying that, we can understand the invisible things of him by the things that are made/created or in other words by what we physically see and comprehend. This most definitely includes understanding his eternal power and Godhead as it is stated in verse 20.
Definition: Godhead n. 1. Divinity; godhood. 2. Godhead
a) The Christian God, especially the Trinity.
b) The essential and divine nature of God, regarded abstractly. (The union of the Father and Son and Holy Ghost in one Godhead)(thefreedictionary.com/godhead)
The trinity is regarded abstractly for those that do not comprehend its nature or make-up.
So back to the question, How can we understand the trinity (the invisible thing) with what God created (what we can see).
The universe is basically made up of 3 parts. Einstein’s theory of relativity revealed the fact that life as we know it consists of three things, time, matter, and space (which is energy).
If one of these elements were removed, the universe as we know it would cease to exist. All three elements are needed so the universe can be (i.e. exist).
Each of these 3 elements (time, matter and space) in turn are made up of 3 parts also.
Time is made up of 3 parts. They are; the past, present and future. If one of these elements were removed, time as we know it would cease to exist. If there is no past the present could not advance into the future to create a past. If there were no present, there definitely would not be a past and future. If there was no future, the present would not be able to move forward.
Matter is made up of atoms. All atoms consist of three basic components, protons, neutrons and electrons. A proton is not a neutron, a neutron is not an electron, and an electron is not a proton. One is not the other, all are part of the same, none can exist without the other (and still remain a complete atom), and yet each is distinct!
Matter is invisible at its core yet we can perceive it.
Two thousand years ago the writer of Hebrew’s wrote:
Heb. 11:3 By faith we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible.
Re-read this until you understand what it saying. By faith we understand…that**,** what is seen**,** was not made**,** out of things which are visible.
(Side note: If man wrote the bible, how could he write something that he didn’t know about. We only discovered atoms at the invention of powerful microscopes. Man is catching up to the bible. This is one example of the divine inspiration of the scriptures.)
We now know this to be a fact because of microscopes. When things are magnified to its minutest level we found it to be energy.
Matter is made up of 3 parts. They are; gases, solids and liquids. If one of these elements were removed, matter as we know it would cease to exist. As an example, take water. In this form it is a liquid. If the element of gases were to be removed, matter as we know it would cease to exist because you would not be able to boil water which once boiled turns into a gas. If solids were to be removed, matter as we know it would cease to exist, because water in a liquid form when frozen would not be able to become/transform into a solid.
Space is made up of 3 parts. They are; length, width and height. Look to the upper corner part of the room you’re in right now and notice the three ‘walls’ i.e. the ceiling, the wall going to the left and the one going to the right. Each wall has an element to it. One supplies the length, one supplies the width and one supplies the height. These three elements make up the concept of space or 3 dimensions. If one of these elements were removed, space as we know it would cease to exist.
A question now comes up. In this example of space, which element (length, width or height) is the most important or which element is the greatest and which is the least?
Would you say that they are all equally the same and important? Could one element be the head or number 1?
When we perceive the ’space’ in a room, we realize that no one element can be greater than another. They all perform the duty they were created to do.
Space is an invisible concept yet we comprehend it by the walls we built around ourselves.
Here is another way to explain it:
Space is a trinity of elements: the length, the width, and the height. The length is not the same element as the width; the width is not the same element as the height; and the height is not the same element as the length. They are separate elements; yet, they are all the one space. They are in absolute perfect harmony consisting of one substance. They are coequal, and copowerful. If any one of the three were removed, there would be no space.
Using the above logic, I now apply it to the concept of the trinity.
God is a trinity of persons: the Father, the Son, and the Holy Ghost. The Father is not the same person as the Son; the Son is not the same person as the Holy Ghost; and the Holy Ghost is not the same person as Father. They are separate persons; yet, they are all the one God. They are in absolute perfect harmony consisting of one substance. They are coeternal, coequal, and copowerful. If any one person of the three were removed, there would be no God.
1 John 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
==============================================================
Some other examples of tri-unity in unity.
Man is triune in nature. He is made up of a spirit, a soul, and a body. The moment that one of these elements is taken out or removed, man as we know him, ceases to exist (in this plane).
1 Thessalonians 5:23 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
How about the human mind?
Scientists tell us that the human mind is the most complex thing in the universe. The is also a trinity. The mind, the will, and the emotions. Your mind, (intellect) is not the same as your emotions. Your emotions are not the same as your will. One is not the other, all are part of the same, none can exist without the other, and yet each is distinct!
==============================================================
Someone had made this observation about the sun once.
Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared, visible, and ultraviolet light. (en.wikipedia.org/wiki/Sunlight)
Infrared light can be felt but not seen. (Holy Ghost)
Visible light can be seen and felt. (The Son)
Ultraviolet light can’t be seen or felt. (The Father)
There are other examples I have that I can use. I hope you have enough information here to help you begin to comprehend and grasp this concept of the trinity.
All the best.
