A digital art representation of a biblical scene based on Mark 13:35-37. The scene depicts a mysterious house under a shifting sky, symbolizing different times of the day: evening, midnight, pre-dawn when the rooster crows, and dawn. Off in the distance, a figure approaches, alluding to the unexpected return of the house owner. Nearby, people are seen on vigilant watch, trying to stave off sleep, emphasizing the directive to 'Watch!'. The sky, people, and house should be rendered with digital techniques, with a combination of pixel-like patterns for a modern digital feel and gentle gradients to portray the changing times of the day.
