St. Martin's History Moment I

In the sanctuary, St. Martin's has an old stained glass window of which the middle panel is a representation of the following picture.

 The Light of the World (1851–3) is an allegorical painting by William Holman Hunt 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 by Divine command, and not simply as a good Subject."[1] The door in the painting has no handle, and can therefore be opened only from the inside, representing "the obstinately shut mind".[2] Hunt, 50 years after painting it, felt he had to explain the symbolism.[3]   from Wikipedia
