The Good Shepherd
The subject of this painting is probably the shepherd presented in Luke 15:1-7. In this passage, Jesus tells about a shepherd who loses one of his one hundred sheep. The shepherd then leaves the other sheep and goes to find this lost sheep. He rejoices when he finds it. The story is meant to exemplify the way in which God rejoices when even one sinner repents.
Oertel, Johannes Adam Simon, 1823-1909
