Create a respectful, devotional Christian themed artwork. The scene shows a symbolic representation of the biblical verse Matthew 3:12. On one side, depict harvested wheat being gathered into a garner, illustrating prosperity and bounty. On the other side, depict chaff being consumed by ravenous, unquenchable fire, signifying purification and judgement. Held resting in Jesus' hand is a fan, a tool of separation and cleansing. The primary artistry technique should be an emulation of soft, delicate watercolor strokes. Mindful to not include any textual elements within the imagery, the art should speak its message purely through visual symbolism.
