It’s the idea that counts, not your drawing skill.
Illustrations pertaining to your verses are particularly welcome and meaningful, and help to orient viewers to the narrative. Although you may not – or may – be a Biblical scholar, or you may not – or may – be comfortable with picture-making, there are several ways of illuminating the same story.
Example A: Genesis 1: Creation Day 4: separating day and night.


Example B: Genesis 4: Cain & Abel


Explore a variety of sources
This far-from-definitive list suggests some directions you might take to better understand your verses. The more you grapple with the text, the more interesting your illumination ideas will be. These are suggestions only, not an endorsement of a particular interpretive orientation or supplier.
