Prompt
Generate a realistic portrait image of Charles Sheldon, an American Congregationalist minister and author, in a 19th-century style, sitting in a study with books and papers around him, wearing formal attire, with a thoughtful expression, and a subtle hint of a cross or Christian symbols in the background, reflecting his devotion to Christianity and the Social Gospel movement, which he is known for coining the phrase 'What Would Jesus Do?' as a guiding principle.
