"Today it is possible to immunize individuals against conditions that once were disabling—even deadly. One medical method by which acquired immunity is conferred is inoculation. The term inoculate is fascinating. It comes from two Latin roots: in, meaning “within”; and oculus, meaning “an eye.” The verb to inoculate, therefore, literally means “to put an eye within”—to monitor against harm."
"An affliction like polio can cripple or destroy the body. An affliction like sin can cripple or destroy the spirit. The ravages of polio can now be prevented by immunization, but the ravages of sin require other means of prevention. Doctors cannot immunize against iniquity. Spiritual protection comes only from the Lord5—and in his own way. Jesus chooses not to inoculate, but to indoctrinate. His method employs no vaccine; it utilizes the teaching of divine doctrine—a governing “eye within”—to protect the eternal spirits of his children."
