The reason of a commandment, whether positive or negative, is clear, and its usefulness evident, if it directly tends to remove injustice, or to teach good conduct that furthers the well-being of society, or to impart a truth which ought to be believed either on its own merit or as being indispensable for facilitating the removal of injustice or the teaching of good morals. There is no occasion to ask for the object of such commandments; for no one can, e.g., be in doubt as to the reason why we have been commanded to believe that God is one; why we are forbidden to murder, steal, and to take vengeance, or to retaliate, or why we are commanded to love one another. But there are precepts concerning which people are in doubt, and of divided opinions, some believing they are mere commands, and serve no purpose whatever, whilst others believe that they serve a certain purpose, which, however is unknown to man. Such are those precepts which in their literal meaning do not seem to further any of the three above-named results: to impart some truth, to teach some moral, or to remove injustice. They do not seem to have any influence upon the well-being of the soul by imparting any truth, or upon the well-being of the body by suggesting such ways and rules as are useful in the government of a state, or in the management of a household. ...I will show that all these and similar laws must have some bearing upon one of the following three things, viz., the regulation of our opinions, or the improvement of our social relations, which implies two things, the removal of injustice, and the teaching of good morals.

Those who believe that... detailed rules originate in a certain cause, are as far from the truth as those who assume that the whole law is useless.

You will find that there is no other difference of opinion as regards any portions of the Universe, except that the philosophers believe in the Eternity of the Universe and we believe in the Creation. Note this.

It is not unreasonable to assume that the works of God, their existence and preceding non-existence, are the result of His wisdom, but we are unable to understand many of the ways of His Wisdom in His works. On this principle the whole Law of Moses is based; it begins with this principle: "And God saw all that He had made, and behold, it was very good" (Gen. i. 31); and it ends with this principle: "The Rock, perfect is His work" (Deut. xxxii. 4). Note it.

Know that the difficulties which lead to confusion in the question what is the purpose of the Universe or of any of its parts, arise from two causes: first, man has an erroneous idea of himself, and believes that the whole world exists only for his sake; secondly, he is ignorant both about the nature of the sublunary world, and about the Creator's intention to give existence to all beings whose existence is possible, because existence is undoubtedly good.

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" (Eccl. iii. 11)... 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.

The philosophers likewise assume that in Nature there is nothing in vain, so that everything that is not the product of human industry serves a certain purpose, which may be known or unknown to us.

After having explained this division, I contend that no intelligent person can assume that any of the actions of God can be vain, purposeless, or unimportant. According to our view and the view of all that follow the Law of Moses, all actions of God are "exceedingly good."

Actions are divided as regards their object into four classes; they are either purposeless, unimportant, or vain, or good.

This is the way how we have to understand the accounts of trials; we must not think that God desires to examine us and to try us in order to know what He did not know before. Far is this from Him; He is far above that which ignorant and foolish people imagine concerning Him, in the evil of their thoughts. Note this.
