Create a respectful and devotional Christian-themed image inspired by the Renaissance era. A saint, represented in Caucasian descent, male, stands symbolically separating wheat and chaff on a threshing floor. In one hand, he holds a winnowing fan, and in the other a handful of wheat. The scene shows a garner filled with wheat in the background. On another side, there is a roaring fire consuming the chaff, with the flame expressing an unquenchable nature. The style should be reminiscent of the detailed craftsmanship, balance, and color palette common in the artwork from the Renaissance period.
