"Whatever God desires to do is necessarily done; there is nothing that could prevent the realisation of His will. The object of His will is only that which is possible, and of the things possible only such as His wisdom decrees upon. When God desires to produce the best work, no obstacle or hindrance intervenes between Him and that work. This is the opinion held by all religious people, also by the philosophers; it is also our opinion. For although we believe that God created the Universe from nothing, most of our wise and learned men believe that the Creation was not the exclusive result of His will; but His wisdom, which we are unable to comprehend, made the actual existence of the Universe necessary. The same unchangeable wisdom found it as necessary that non-existence should precede the existence of the Universe. Our Sages frequently express this idea in the explanation of the words, "He hath made everything beautiful in his time" ... This is the belief of most of our Theologians; and in a similar manner have the Prophets expressed the idea that all parts of natural products are well arranged, in good order, connected with each other, and stand to each other in the relation of cause and effect; nothing of them is purposeless, trivial, or vain; they are all the result of great wisdom. ...This idea occurs frequently; there is no necessity to believe otherwise; philosophic speculation leads to the same result; viz., that in the whole of Nature there is nothing purposeless, trivial, or unnecessary, especially in the nature of the spheres, which are in the best condition and order, in accordance with their superior substance."

“We suffer from the evils which we, by our own free will, inflict on ourselves and ascribe them to God, who is far from being connected with them!”

“All the great evils which men cause to each other because of certain intentions, desires, opinions, or religious principles, are likewise due to non-existence, because they originate in ignorance, which is absence of wisdom.”

“Those who are ignorant and perverse in their thought are constantly in trouble and pain, because they cannot get as much of the superfluous things as a certain other person possesses. They as a rule expose themselves to great dangers... for the purpose of obtaining that which is superfluous and not necessary. When they thus meet with the consequences of the course which they adopt, they complain of the decrees and the judgements of God; they begin to blame the time, and wonder at the want of justice in its changes; that it has not enabled them to acquire great riches... for the purpose of driving themselves to voluptuousness beyond their capacities, as if the whole Universe existed only for the purpose of giving pleasure to these low people.”

“Those who desire to be men in truth, and not brutes, having only the appearance and shape of men, must constantly endeavor to reduce the wants of the body, such as eating, love, drinking, anger, and all manners originating in lust and passion; they must feel ashamed of them and set limits to them for themselves.”

“He fully knows His unchangeable essence, and has thus a knowledge of all that results from any of His acts. If we were to try to understand in what manner this is done, it would be the same as if we tried to be the same as God, and to make our knowledge identical with His knowledge. Those who seek the truth, and admit what is true, must believe that nothing is hidden from God; that everything is revealed to His knowledge, which is identical with His essence; that this kind of knowledge cannot be comprehended by us; for if we knew its method, we would possess that intellect by which such knowledge could be acquired. ...Note this well, for I think that this is an excellent idea, and leads to correct views; no error will be found in it; no dialectical argument; it does not lead to any absurd conclusion, nor to ascribing any defect to God. These sublime and profound themes admit of no proof whatever... In all questions that cannot be demonstrated, we must adopt the method which we have adopted in this question about God's Omniscience. Note it.”
