The Trinity is a mysterious concept: one God in three persons. Trying to explain the Trinity in detail, or to devise a model which perfectly illustrates it, inevitably fails. One isn’t three and three isn’t one; mathematics is solid on this point. Is this a problem?
Only if we presume an infinite God may be fully explained in finite terms. Yet the Being Who inhabits eternity, Who created the ten dimensions in which we exist, must be far above, beyond and outside of them. Is it any wonder that we’re unable to create a finite model which perfectly and completely represents Him?
Perhaps this gets at the heart of the 2nd Commandment: “Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.” (Ex 20:4a) Trying to create a physical representation of God, or even a theoretical image, is attempting to create a likeness of Him. Perhaps He’s telling us not to do this because it can’t be done; any attempt to fully define Him will ultimately fail.
Creating an accurate image of God is not only impossible, it’s evidently harmful, for in reducing the Godhead to any likeness of any thing in the universe is to perceive Him as less than He truly is, to diminish Him; this corrupts our worship and tarnishes our perception of Him.
Perhaps this is one reason God hates idolatry so much: it replaces God with something paltry, something small and finite. Our tendency to try to contain God in a physical – even a theological – box leads us into error. Perhaps it’s our way of trying to control Him.
We may content ourselves in accepting the fact that God reveals Himself as a unity (De 6:4) as well as a plurality. (Ge 1:26a) There can be no true logic implying God can’t be this way. God has revealed Himself as a triune Being, each Person of the Godhead uniquely and purposefully, yet ascribes to each Person all the attributes of the entire Godhead. We must not separate these Persons: they are one; yet we must allow for distinctness within them, for that is how Jehovah has revealed Himself.
Our perception of God is foundational in our spiritual lives and impacts our way more than we can possibly imagine. No possible description of Him can be too glorious, too majestic; it is impossible to have too high a view of God. We must not place any artificial limits on our conception of God, but let our spirits soar continuously higher in seeking Him.
Staying faithful to the scriptures here, and living within it’s prescription for us, is freedom of a most profound kind.
Here’s a link to a message about the Trinity which I found to be very helpful.
One fact he points out, which I have long overlooked, is that God the Father indwells each believer: “One God and Father of all, who is above all, and through all, and in you all.” (Ep 6:4)
