No complex exegesis here. This is more of a story. I was driving to work one morning (I have a long drive through beautiful rural hill/mountain country) and the sun was in my eyes. I was asking God about the Trinity. I’d heard many explanations which did not satisfy me: the egg (no, please don’t groan) comes to mind. The following is the picture I believe He gave me, and perhaps some of you will at least find it interesting.
The sun represents the Father. If you think about the nature of light and the nature of seeing with human eyes, you will realize that the sun (and all things, really) is invisible. We cannot see it. This seems to me particularly obvious regarding the sun, as it is the source of the light. We can only see the light that comes to us from the sun. We can feel its warmth, and it allows us to walk about without stumbling. Its light is the source of all our food, all our energy – our physical life, really. But we can’t see it. We can only see the light of the sun as it comes to us.
The light of the sun represents Jesus, who is eternally begotten of the Father. He is always coming forth from the Father. He gives us life because the Father has granted that He should have life within Himself. He is the light of every man, and He comes into the world. He particularly came in the Incarnation. He is not the sun, but in a sense, He is the sun. He is the Son.
The Holy Spirit doesn’t seem to me quite as clear, but He is the Spirit, after all. Light comes to us in such mysterious ways; as a particle; as a wave. It brings warmth and illumination, allows us to perceive colors, performs certain actions which are still cloaked in darkness (so to speak) such as becoming food to plants and destroying certain microorganisms and causing our skin to form vitamin D. The light, even as it comes, is still one with the sun. There is a dance between them, and that dance of love is the Holy Spirit.
Not dogma, not stunning exegesis, but as you are talking about the Trinity, I venture to share it. This picture speaks clearly to me. I love when God talks to me in pictures. Makes it so much easier for me to follow Him.
