Consider the case of a person who possesses a variety of different skills. He may know how to do metalwork and painting and how to make music. We might say that the reason why he does all these different things is because this is what he knows, and if he knew more, he would do more. We are not obliged to find any connection between one field of expertise and another, or between different examples of the person’s work in various spheres. What he knew, he did.
But the Holy One, blessed be He, has made so many creatures. Should we therefore say that he made just as many creatures as the number of great skills He possesses, like the man who knows how to do metalwork, paint and make music, and who does each of the things he does because he possesses the requisite expertise? The immediate objection can be raised: “Have you then exhausted all the praises of your Master?” (Berachot 33b) Does He possess no other knowledge except that exhibited by the work we see? Why did He make just so many creations and no more? Why did He not make just one?
