John Henry Jowett, a British preacher of an earlier generation, said this about gratitude: "Gratitude is a vaccine, an antitoxin, and an antiseptic." What did he mean? He meant that gratitude, like a vaccine, can prevent the invasion of a disgruntled, discouraged spirit. Like an antitoxin, gratitude can prevent the affects of the poisons of cynicism, criticalness, and grumbling. Like an antiseptic, a spirit of gratitude can soothe and heal the most troubled spirit.
