These poor sheep aren’t lost. They’re hiding. And they’re in for a beating.
Sometimes you think people are lost when in fact they’ve left you intentionally.
The whole point of the story of the lost sheep is that the shepherd was overjoyed when he found it. And it is presumed that because he was a good shepherd the sheep was overjoyed too.
Don’t scold or punish people for leaving you. It’s that attitude that probably encouraged them to “get lost” in the first place.
