If they say, “Infinite, as in the future,” they have acknowledged the existence of an infinity in the past, under the condition on which an infinity can exist: namely, that it does not exist all at once and that space does not come to an end.

If they say otherwise, they have ruled out eternal acts for the One whose existence is eternal. The same consequence must then apply to His knowledge of temporal events and His will concerning them: what He actually knows—and likewise what He wills—would be finite, though potentially infinite.

As regards the past, this is because they do not allow an infinite number of acts; as regards the future, it is because the infinite exists for Him only potentially. Yet this is not a position they profess.

If they say, “His will and the objects of His knowledge are actually infinite,” they have conceded that an actual infinity enters into existence.

He said: “All of this unsettles the beliefs of those who follow the revealed Law and obstructs the purpose for which these matters were made known to them: that they should hold firm convictions concerning them and be good people. For whoever lacks firm conviction concerning these matters is not a good person.”
