The Light of the World was painted by Holman Hunt between 1853 and 1854. It depicts Jesus knocking on a door without a handle which can only be opened from the inside. According to Holman Hunt, this symbolises 'the obstinately shut mind'.
The original painting is at Keble College, Oxford. However, a second version, which Holman Hunt painted towards the end of his life, hangs in St. Paul's Cathedral in London.
