16 And besides, when we are talking of indifferent matters, if we see those that are in company do not attend, we call what they do an insult; but do we consider that we are provoking God, if, while He is discoursing of such things as these, we despise what is said, and look another way?
Why, he that is grown old, and has travelled over much country, reports to us with all exactness the number of stadia, and the situations of cities, their plans, and their harbors and markets; but we ourselves know not even how far we are from the city that is in Heaven. For surely we should have endeavored to shorten the space, had we known the distance. That city being not only as far from us as Heaven is from the earth, but even much farther, if we be negligent; like as, on the other hand, if we do our best, even in one instant we shall come to the gates thereof. For not by local space, but by moral disposition, are these distances defined.
But you know exactly the affairs of the world, as well new as old, and such too as are quite ancient; you can number the princes under whom you have served in time past, and the ruler of the games, and them that gained the prize, and the leaders of armies, matters that are of no concern to you; but who has become ruler in this city, the first or the second or the third, and for how long, each of them; and what each has accomplished, and brought to pass, you have not imagined even as in a dream. And the laws that are set in this city you will not endure to hear, nor attend to them, even when others tell you of them. How then, I pray you, do you expect to obtain the blessings that are promised, when thou dost not even attend to what is said?
