One of the core beliefs of true Christian faith is the doctrine of the Trinity. This is simply defined: There is only one God, who is revealed in three, eternally-existent persons, the Father, the Son, and the Holy Spirit. All three are separate Persons, all three are God, yet there is only one God.
This concept can be difficult for some to understand and accept, which has led to many people rejecting this truth. One of the signs of a cult (false religion claiming to be Christian) is the denial that Jesus Christ, as the only begotten Son of God, is fully God. One of the reason the Jews reject Jesus as their Messiah is for this reason. Muslims, who claim to worship the same God as the Jews, also deny that God has a Son – which is why they hate Christians so much, because of the Antichrist spirit that permeates their religion.
Romans 1:20: For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead…
His majesty and omnipotence is seen in His magnficent, seemingly infinite creation. We see it from the universe, the brilliant galaxies and stars and planets. We see it clear down to the microscopic level and even smaller – the particles that make up the protons, neutrons, and electrons that are the parts of atoms.
God’s justice is also seen in creation. The non-theistic religions (Buddhism and Hinduism) have a concept called karma, which in part teaches that you get back what you dish out. The Bible calls it reaping what you sow, and attributes it to the justice of God. So even false religions see God’s justice at work, but refuse to give God the glory.
Likewise, the tri-une attribute (three-in-one, Trinity) can also be seen in creation. Now some have tried to compare the trinity to a three-leafed clover, or to cutting a fruit pie into three pieces, or other things. But most of these illustrations fall short of explaining the Trinity.
The best representation for the Trinity is the three dimensions of physical space. (Yes, I know that mathematically there are more dimensions, but we can only actually physically see three. His attributes are clearly seen.) This is typically illustrated with a cube.
Each dimension can be separately measured, yet there is only one cube. Further, no matter at what point you choose within that cube, it is represented by three variables that describe its position in relation to each dimension. In other words, no matter where you go in space, it takes all three dimensions to describe where you are – all three dimensions exist at every location. Yet all three dimensions can be measured separately, height, width, depth. A cube is mathematically illustrated as 1 X 1 X 1 = 1, or one cubed equals one. Another way of putting it, there is one space, revealed in three dimensions
The same is true for the Trinity. People get messed up when they try to make the mathematical representation 1 + 1 + 1 = 1, because it just doesn’t add up. Thus they reject this doctrine.
Each “dimension” of the Godhead can be recognized and measured separately. They each have their own role in creation and salvation. The Holy Spirit convicts and guides us. Jesus saved us by His shed blood on Calvary, and all things were created by Him and for Him. The Father is the Director over it all.
Each One is declared to be God in Scripture, repeatedly. Yet the Bible just as clearly says there is only one God. The correct mathematical representation of the Trinity is the same as for space. There is only one God, revealed in three Persons.
