“The heart is a God-shaped blank, and only God can fill it.” That maxim has been around for almost 1700 years, but I’m afraid that today there are not too many people who are familiar with it. Today there are millions of people who are trying to fill it with everything except God, and they do not succeed. Consequently we have seen suicide become endemic, euthanasia on the march, mental disorders of all kinds, depression, despair, hopelessness everywhere. What an incredible truth—only God can fill it. You cannot run a jet plane with tomato juice, and you cannot fill the God-shaped blank of the human heart created by Him, for Him, with anything else at all.
