This painting, known as the Good Shepherd, is by Bernhard Plockhorst, (1825-1907), a German painter and graphic artist. In Germany, Plockhorst is mainly known to experts today, whereas his pictures are still very popular in the United States and their reproductions can be found in many American homes and churches.
In this painting we see Jesus caring for His sheep and carrying a lamb in his arm, perhaps it is too weak or tired to keep up with the flock.
Jesus often described Himself as the shepherd, caring for His sheep. On some occasions He also uses a sheep-herding reference by describing Himself as “the gate”. Read more about the significance of this HERE.
