Wollebius:

But that which is included in the popular jingle,

He commands and he forbids,
Permits, advises, and fulfills,

may be loosely called by the designation of divine will. Just as the edicts of a magistrate are called his will, so the designation of will may be given to precepts, prohibitions, promises, and even deeds and events. Thus the divine will is also called that which God wants done [voluntas signi], because it signifies what is acceptable to God; what he wants done by us. It is called “consequent” because it follows that eternal antecedent; “conditional” because the commandments, prohibitions, warnings, and promises of God all have a condition of obedience or disobedience attached to them. Finally, it is called “revealed,” because it is always explained in the word of God. It must be observed that this sort of distinction does not postulate either really diverse, or contradictory, wills in God.
