On Limited Atonement

Look, the atonement is limited. It is limited in its efficacy. It is limited in its efficiency. It is limited in its application. It is limited obviously. The only question is, who limits it? And the only right answer is that God limits it and that He limited it in this sense, that it was an actual payment in full of all the sins of all the people who would ever believe. And the people who would ever believe would believe because of His mighty work on their hearts based upon His sovereign eternal purpose.
-John MacArthur
