Create an abstract digital artwork that represents the concept illustrated in the bible verse Luke 6:45. Depict two contrasting men -- one virtuous man emanating positivity from his heart, representing the 'good treasure', and another man radiating negativity, symbolizing 'evil treasure'. The virtuous man is producing good from the abundance of his heart, whereas the malevolent individual is spewing out evil. This artwork should embody the saying, 'for of the abundance of the heart his mouth speaketh', with both men having words flowing out of their mouths representing their respective energies.
