The writings of G. D. Watson continue to bring enlightenment and spiritual help to Christians from all walks of life. Each chapter of Soul Food brings instruction and inspiration on a particular truth. The subjects covered are wide ranging, as can be seen from the following selection of chapter titles: "Loaded Words," "Lukewarmness," "Feeding Our Faith," "The Benefit of Deep Crucifixion," "Fretting Over Ourselves," "Little Things," "Alone with God," "Climax of Sorrow," and others.

Here is a short excerpt from the first chapter: "Faith is the digestive organ of the soul. It is by faith that the truth is dissolved and prepared to make living substance. Unless we have real, strong faith, the truth we perceive is not converted into living substance. A spiritual dyspeptic is one who has large perceptions of truth, but no adequate faith to digest it and turn it into experience. Just as the stomach of the body is often ruined by alcohol, tobacco, and other poisons and stimulants, until its digestive organs are ruined, so the stomach of the soul is often ruined by mental stimulants, such as novels, philosophy, and false doctrines, until the digestive power of faith is well-nigh destroyed."
