In Matthew 18:12-14, Jesus shares a parable about a shepherd who has a hundred sheep. When one sheep goes missing, the shepherd leaves the ninety-nine to search for the lost one. This illustrates the importance of every individual and the lengths one will go to for their well-being. The passage emphasizes that just as the shepherd cares deeply for each sheep, God values every person. The message conveys that no one is insignificant, and God rejoices when even one lost soul is found and returned to the fold.
