" The apostle Paul peremptorily, over and over again, tells us that salvation is not by works; nay, he tells us that it is not by works and grace put together; he testifies that the two principles neutralise and kill each other, and that a man must either be saved wholly as the result of God’s favor, or else he must be saved altogether as the result of his own merit, for the two principles cannot in any way be combined. "
