Lost sheep

Jesus told them this parable: "Suppose one of you has a hundred sheep and loses one of them. Does he not leave the ninety-nine in the open country and go after the lost sheep until he finds it? And when he finds it, he joyfully puts it on his shoulders and goes home.
Luke 15:3-6a

I am the good shepherd. The good shepherd lays down his life for the sheep.
John 10:11
