VII. But the fact that he does exist, though it is comprehensible from the mere name of existence, is nevertheless not understood by every one, or at all events not in the best way by every one; but some men have expressly and wholly denied that there is any deity at all; while others have doubted and hesitated, as if they were unable to affirm with certainty whether he has any existence or not. Others again, who have more through habit than from any exertion of their reason, received ideas about the existence of God from those who have brought them up, have seemed to be pious by a sort of felicity of conjecture, if they have stamped their piety with an impression of superstition. (41) But if any men, by a great depth of real knowledge, have been able to represent to themselves the Creator and Governor of this universe, they, according to the common phrase, have advanced upwards from below; for having entered into this world as into a city regulated by admirable laws, and having beheld the earth consisting of mountains, and of plains, and full of seed-crops, and of trees, and of fruits, and also of all kinds of animals; and beholding also seas, and ports, and lakes, and rivers of all sorts, whether proceeding from winter floods, or from everlasting springs, diffused over the surface of it, and the admirable temperature of the breezes and of the atmosphere, and the harmonious changes and well-ordered revolutions of the seasons of the year, and beyond all these things, the sun and moon, the planets and fixed stars, and the whole heaven, and all the host of heaven in its proper arrangement, and, in fact, the whole real world revolving in admirable order and regularity: (42) admiring, and being struck with awe and amazement at these things, they are come to form notions consistent with what they behold, that all these beautiful things, excessive as they are, and of such admirable arrangement and contrivance, were not produced spontaneously but were the work of some maker, the Creator of the whole world, and therefore that there must of necessity be a superintending providence. For it is a law of nature, that the Creator must take care of what he has created. (43) But these admirable men, so superior to all others, have, as I said, raised themselves upwards from below, ascending as if by some ladder reaching to heaven, so as, through the contemplation of his works, to form a conjectural conception of the Creator by a probable train of reasoning. And if any persons have been able to comprehend him by himself, without employing any other reasonings as assistants towards their perception of him, they deserve to be recorded as holy and genuine servants of his, and sincere worshippers of God. (44) In this company is the man who in the Chaldaean language is denominated Israel, but in the Greek "seeing God;" not meaning by this expression seeing what kind of being God is, for that is impossible, as I have said before, but seeing that he really does exist; not having learnt this fact from any one else, nor from anything on earth, nor from anything in heaven, nor from any one of the elements, nor from anything compounded of them, whether mortal or immortal, but being instructed in the fact by God himself, who is willing to reveal his own existence to his suppliant. (45) And how this impression was made, it is worth while to see by the observation of some similitude. Take this sun, which is perceptible by our outward senses, do we see it by any other means than by the aid of the sun? And do we see the stars by any other light than that of the stars? And, in short, is not all light seen in consequence of light? And in the same manner God, being his own light, is perceived by himself alone, nothing and no other being co-operating with or assisting him, or being at all able to contribute to the pure comprehension of his existence; (46) therefore those persons are mere guessers who are anxious to contemplate the uncreated God through the medium of the things which he created, acting like those persons who seek to ascertain the nature of the unit through the number two, when they ought, on the other hand, to employ the investigation of the unit itself to ascertain the nature of the number two; for the unit is the first principle. But these men have arrived at the real truth, who form their ideas of God from God, of light from light.
