Illustrate an art nouveau scene that depicts the concept taken from Romans 13:8: owing nothing to anyone except in expressing love to one another. Display this concept through vignettes. In one vignette, show a person of Caucasian descent sharing bread with another person of Middle-Eastern descent, both males, to symbolize equals sharing their resources. Show another where a female of Hispanic descent stoops with grace to help an older Asian woman up the steps as an act of kindness. A final scene can include a black male child offering his seat to a white elderly man on a crowded bus. Ensure the scene reflects a sense of respect and devotion to Christianity.
