The 99 Sheep story is ridiculous

I don’t know about sheep herding, but what sane shepherd would leave 99 sheep to go look for a single one missing. When he’s back he won’t have a hundred for sure. That will make him a bad shepherd. This just adds to the lists of parables and stories that just don’t make any sense, I think they’re there just to train you into believing random things and accepting illogical pretenses. You’re supposed to feel grateful that the shepherd went great lengths to rescue you, but they’re stating right there that he doesn’t really care about your well being once you’re in the herd. If this parable works in anyway is just to point that out.
