In the study of this marvellous passage (verses 28–30) one fact is generally passed by in silence. It is this:
The authoritative advice Jesus gives is not only good for the soul; when heeded it also greatly benefits the body. The rest—peace of heart and mind—which Jesus here provides is the very opposite of the aggravated mental stress that sends so many people to doctors, hospitals, and death. Absence of peace, whether in the form of anxiety or of rancour and vindictiveness (the lust to “get even”), may lead to ulcers, colitis, high blood pressure, heart attacks, etc.
The teachings of Christ, if taken to heart, have a curative effect on the entire person, soul, and body. He is a complete Saviour!
