Depict an abstract image reflective of the message in Romans 11:18 from the Bible. The design should echo the mood and motifs typically found in digital art. Eschew the usage of text or words in the composition. The interpretation should be respectful, abounding with a sense of reverence, similar to what one would find in devotional Christian art. As a reference, include elements such as ethereal light, nuanced color gradients, and symbols or metaphoric representations of biblical teachings without directly quoting the scripture.
