Create a respectful and devotional representation of the Christian themes in Matthew 22:37-39, without directly using text or words. Depict this using watercolor style. This scene should capture the essence of wholehearted devotion and love for God, signified by a heart, a head, and a soul, paired with acts of benevolent love for a neighbor, analogous to self-love. The elements should be arranged in an aesthetically pleasing manner that communicates the depth of the greatest commandment. The image should give viewers a sense of religious devotion and respect for Christianity.
