My personal favorite is to START (!) with the concept of Infinity.
That’s kind of a big chunk of a concept to put your arms around. Especially for starters.
But go with that…
God in infinite in time. So God is not bound to any one particular concept of time. You and I look at time as linear. We are born at date “A” and die at date “Z”. We grow, lose our baby teeth, go to school, get jobs, get married, have families, and die. Linear. Simple. For me, time is 80 years long. I have no personal knowledge of what happened before I was born. I hear stories and read books. Old movies are only in black and white; did things occur in “color” before I was born?
But the earth is around 10 billion years old. So what happened before the big bang? What happened 10 billion years before that? What is a year, anyway? It’s the passage of the earth around the sun. What is time???
What if time, in the cosmic sense was something other than linear. What if, in God’s Eye View, hundreds of billons of years to us, never ending, everything is so “small” and so close together that everything seems to take place simultaneously.
What if time was curved (as some scientists suggest) [whatever that means - and I don’t understand it – or suppose time was a “powder” so you could “step” or move from one particle of time to any other particle of time at any time of your own choosing.
God is infinite in space. And I have NO idea what space is… I happen to be three dimensional. (Four, if you include “time”.)
If I existed in ONE dimension, like the period at the end of this sentence, how would I explain THREE dimensions to one of my one dimensional friends. How would I explain time or color to my one-dimensional friends?
If I never travel more than five miles from home, then the Earth is flat! How can I possibly explain a spherically shaped earth?
If I look at the Earth from the Moon, it looks like a big blue marble. How can I possibly explain that it is really a big liquid centered chocolate (7000 miles in diameter) with a paper thin crust (30 miles thick) and a core that is around 5000 degrees hot liquid molten metal, rock and other stuff? And with an atmosphere that is about 3-5 miles thick. And it has been blowing up for millions of years with maybe 3000 volcanos (2000 underwater) and the crust “drifts”??? … moves around like pond scum???
What if there are an infinite number of dimensions?
God is infinite in creativity. He made aardvarks, platypuses, camels. He made this planet and put it into a “perfect” orbit around the “Sun”… and braided the rings of Saturn… He made us, but we are actually made of molecules and “DNA” (whatever is DNA???). And the molecules are made of atoms. And atoms are just statistical distributions of electrical charges separated by about 99.999999999% empty space. In a sense I am 99.99999999999% empty space, with a tiny amount of electrical charge AND free will.
How did THAT happen???
For a reason that we CANNOT fathom, God, the Infinite, Infinity Itself, took on human form. The incarnation. God somehow “detached” part of Himself … as Jesus… the second person of the Blessed Trinity… [“The Father and I are one…”] The humiliation of it… is overwhelming. WHY WOULD HE DO THAT? It would be like you or me deliberately taking on the form of one speck of dust.
We have NO IDEA of why God did that. Maybe being infinite is SO COOL that God wanted to share part of that infinity with someone else.
Then God let Himself be tortured to death… whipped like a low life and crucified… WHY!!!
We have a few answers… but not very many.
The word “love” gets over used and is not defined anywhere, except in parables… the Good Samaritan… which was a fictional story…
So, anyway, when Jesus says there is a third member of the “team”, I believe it.
