If you treat your sketchbook as a book of answers you’ll suffocate from the presence of the inner judge, who will demand a certain finished quality to those sketched answers. No, see your pencil as a questioning stick. It is a divining rod, doodling among the surface textures of what you see in front of you, stopping to drop deeper into the picture when it passes over the pixel that really pulls at your attention.
So your drawing is questioning and answering all at once and you are utterly given up to the process. Whatever the page looks like at the end of the day is the right answer.
It might be that what God sees in the treeline at dusk is not what you see. We are not pantheists. But we are also not docetists; it is certain that your path to seeing what God sees runs through your own vision, and not around it.
