They say that it’s darkest just before the dawn. Perhaps that’s physically true, but they usually don’t mean a sky without sunlight. They’re saying that rescue, recovery, revelation, or some other relief we seek comes only after – shortly after – we are stretched to our personal limits.
That was Joseph Smith’s experience in the grove, for example. Just as he felt himself on the verge of destruction, the pillar of light appeared (JS-H 1:16). We trust in our own happy outcomes too; in the end our darkness will be just that thing that happened for a while before the lights came back on.
That’s true, but it can be difficult to believe, when all we see and feel is darkness.
