I need to switch some things around for the sake of the analogy, so here we go.
Imagine the ocean is freshwater and all the rivers flow the opposite direction. All the water that everyone and everything needs comes from this ocean far, far away. The little tributaries make it all the way to your town so that eventually the water gets to your grass and your kitchen sink.
But you don’t know any of this. All you know is that when you turn on the faucet, water comes out.
Then you start noticing things. The water at your house tastes exactly the same as it does at my house. And your mom’s. And all your friends’.
You go for a traipse through the woods and find a miniature creek. The water is very clean and clear, satisfying to a dry, sticky mouth. Then you cross another, and another. It starts coming clear to you that all of this water, and in fact all water, is the same. It taste the same because it comes from the same source.
Then someone tells you there is an ocean far away, and slowly the pieces all begin to connect. You have never seen the ocean or the pathways by which its water gets from there to here, to nourish the trees and the people and the animals. But you have learned that the sea is so vast you could put everything on the entire globe that’s above sea level into the ocean ten times over and you still wouldn’t fill it up.
This is what everything looks like to me. Everything has God’s fingerprints all over it, and it could not be another way. He created everything for his glory, so at the end of the day, everything necessarily has his glory in it if you have eyes to see it, and it all points back to that Ocean of glory whence it came, which is Him.
The tributaries are literally everything that exists, from the strength of man to the beauty of woman to the preciousness of children, from relationships with friends to the chemistry of how tastebuds experience flavor to the newest music to manned flight to the moon. If it was a Venn diagram, literally everything would be inside the circle of Things That Showcase God’s Glory.
