Musar su Geremia 10:14

Since it has been made clear that service to God must be with three things: with fear, with wisdom, and with love, we recognize that these three are given by one shepherd, and that is reason, for reason contains all three and other powers as well. For it is obvious that reason contains wisdom and love and the awareness that the rational person should in all things love the righteous path, lest he add to any of them more than is fitting or diminish more than is fitting. We learn from this that according to the perfection of the reason of man will his service to God become whole, and that what is lacking in the perfection of his service to God is lacking in the man’s reason and knowledge. If the service be perfect there is no doubt that the knowledge of their possessor is complete. For Scripture says with regard to sins and sinners (Jeremiah 10:14), “Every man is proved to be brutish, without knowledge,” and it says (Isaiah 44:18-19), “They know not, neither do they understand; for their eyes are bedaubed, that they cannot see, and their hearts, that they cannot understand. And none considereth in his heart, neither is there knowledge nor understanding.” The Prophet means that the service must be with the power of wisdom, as it is said (Psalms 111:10), “Fear of the Lord is the beginning of wisdom.” And this is a sign that the service of God, blessed be He, is the goal of reason and wisdom and that those who forsake God are fools. If someone were to say, “Behold you see the wicked, that even among them there are wise and intelligent men in every branch of wisdom. How can you say of them that they are fools or lacking in mental power?” Our answer would be: “When a wise man is visited by misfortune and thereupon does a thing which he has never done before, but suddenly realizes that through this thing salvation will come to him, it is a sign of his previous folly.
