Create a respectful and devotional Christian artwork that draws insight from Matthew 3:12. The scene should depict a figure holding a fan in one hand, thoroughly purging a floor. In another area of the piece, the figure is gathering wheat into a garner. Another part of the scene illustrates the figure burning chaff with an unquenchable fire. This should convey spiritual purification and the separation of good from evil. Render this in a digital art style. Please avoid using explicit text or words in the image.
