So why take on the burden of matters which you cannot answer for? You are only making unnecessary problems for yourself. - Epictetus

Either God wants to abolish evil, and cannot; or he can, but does not want to.

Until you know their reasons, how do you know whether they have acted wrongly?

It is not wisdom that contrives arms, or walls, or instruments useful in war; nay, her voice is for peace, and she summons all mankind to concord. It is not she, I maintain, who is the artisan of our indispensable implements of daily use. Why do you assign to her such petty things? You see in her the skilled artisan of life. The other arts, it is true, wisdom has under her control; for he whom life serves is also served by the things which equip life. But wisdom's course is toward the state of happiness; thither she guides us, thither she opens the way for us. She shows us what things are evil and what things are seemingly evil; she strips our minds of vain illusion. She bestows upon us a greatness which is substantial, but she represses the greatness which is inflated, and showy but filled with emptiness; and she does not permit us to be ignorant of the difference between what is great and what is but swollen; nay, she delivers to us the knowledge of the whole of nature and of her own nature. She discloses to us what the gods are and of what sort they are; what are the nether gods, the household deities, and the protecting spirits; what are the souls which have been endowed with lasting life and have been admitted to the second class of divinities, where is their abode and what their activities, powers, and will.
