God alone is omniscient. Every creature is finite, and feels this in its intelligence; so the knowledge of the angels, extensive as it is, is subject to limitations. God alone, for instance, holds the wonderful power of reading futurity. His future acts, and the future acts of the liberty of man are known to Him alone. Our Lord tells us that the date of the day of judgment is unknown even to the angels in heaven; many other things must also be hidden from them, including probably the ultimate destiny of individual men. So far as they know such things, we must suppose that they are revealed to them specially by God, when the knowledge is necessary for our utility and for their service. It is surmised that after their creation and before their trial they did not fully know what the result would be in the way of reward or punishment. As to affairs on earth their natural powers would often enable them to conjecture truly as to future events, proceeding as men do from past experience and the knowledge of antecedent causes. We may safely assume that the bad angels would be less likely to receive any knowledge of the future from God, and they could only form a judgment about it from their observation of natural laws.
