There is a famous painting by 19th century artist William Holman Hunt entitled “The Light of the World.” It pictures Jesus holding a lantern and knocking on a door. The door is overgrown with vines and obviously has not been opened in some time. This, of course, evokes the saying the Book of Revelation: “‘Behold, I stand at the door and knock. Interestingly, the artist does not show a door knob on the door. If it is going to be opened it will be from the inside. That depicts how faith works — Jesus desires to come into our lives and fill us with light but we have to open the door. Jesus wanted to have dinner with Zacchaeus but could only enter at Zacchaeus’ welcome.
