Imagine an illustration that captures the essence of Acts 15 from the Christian Bible. The image should be rendered in a style that aligns with the principles of digital art. Think bold colors, soft gradients, and defined shapes. Ensure the depiction is respectful and reverent, showcasing key moments or symbols correlated with the chapter. Remember, no text or words should be used in the artwork. The entire message should be conveyed solely through the graphics and design elements.
