Create a devotional Christian watercolor painting showcasing the moment in Luke 10:19 where authority is given to overcome all the power of the enemy. The scene should feature symbolic images of snakes and scorpions being trampled underfoot, representing the power of faith overcoming adversity. Make sure the mood of the piece is respectful and emphasizes the triumphant, hopeful nature of the verse. Use colors that are rich and embody a sense of spirituality. Definitively avoid any text or words in the artwork.
