Create an artful depiction inspired by Genesis 15:4. Showcase a believer at the moment of receiving divine revelation, indicating that his true heir shall be of his own lineage. It should capture the pivotal nature of the message and the awe in the believer's face using the techniques and feel of the Renaissance era. No text should be included in the image, and the manifestation of the message should be visual and not literal. The scene should be respectful and devotional to Christianity.
