The Light of the World (Hunt)
The Light of the World (1851–1854) is an allegorical painting by the English Pre-Raphaelite artist William Holman Hunt (1827–1910) representing the figure of Jesus preparing to knock on an overgrown and long-unopened door, illustrating Revelation 3:20: "Behold, I stand at the door and knock; if any man hear My voice, and open the door, I will come in to him, and will sup with him, and he with Me". According to Hunt: "I painted the picture with what I thought, unworthy though I was, to be divine command, and not simply a good subject." The door in the painting has no handle, and can therefore be opened only from the inside, representing "the obstinately shut mind".
