234. THE LAWS OF PERMISSION ARE ALSO LAWS OF THE DIVINE PROVIDENCE
There are no laws of permission by themselves or separate from the laws of the Divine Providence: they are indeed the same. When, therefore, it is said that God permits, this does not mean that He wills, but that He cannot avert on account of the end, which is salvation. Whatever is done for the sake of the end, namely, salvation, is according to the laws of the Divine Providence. For, as was said before, the Divine Providence, keeping this end continually in view, is constantly moving in ways different from and contrary to man's will. Therefore, at every moment of its operation or at every step of its progress, when it perceives man to deviate from this end, it directs, bends and disposes him in accordance with its laws by withdrawing him from evil and leading him to good. It will be seen in what follows that this cannot be done without permitting evil. Moreover, nothing can be permitted without a cause, and such a cause is only to be found in some law of the Divine Providence which explains why it is permitted.
