It got me to thinking about rocks; specifically about wet rocks...
More than once I've sat on the shore of a body of water and noticed how different a rock can look when it's wet as compared to when it's dry.
In every case, the change I have observed is that the wet rock is prettier. Its natural features of stripes or speckles or color variation (or even just its natural color) are enhanced and given definition by the presence of water.
When they are dry, the rocks all look more or less alike, but when they are wet they are unique.
My husband found a large pretty stone in a river last summer and wanted to bring it home for our garden, but once it dried out it became quite dull. He has actually decided that he'd like to put some kind of lacquer on it so that it will maintain its 'wet' look even when not submerged. Because it's a better or more appealing rock when it is paired with water.
Water is, in many senses, the antithesis of stone. Stone is simple, solid, stable, and more or less immoveable. Water is fluid and flowing, changeable, and sensitive to its surroundings.
The only way for a rock to maintain the beauty of the water is for it to be submersed repeatedly or at length. In other words, it is immersion in opposition that creates the beauty.
In longer spans of time water can change rock even more, by shaping and smoothing it through gradual erosion. I realize the metaphor here isn't perfect, but I did at least want to give a nod to the idea that it's not just about beauty or definition.
The point is that opposition, though unpleasant or even painful in the moment, can be beneficial or improving in the longer run. It can show us the best version of ourselves. It pushes us through the changes that refine us.
