De Virtutibus

But this man, having formed a proper conception of him in his mind, and being under the influence of inspiration, left his country, and his family, and his father’s house, well knowing that, if he remained among them, the deceitful fancies of the polytheistic doctrine abiding there likewise, must render his mind incapable of arriving at the proper discovery of the one true God, who is the only everlasting God and the Father of all other things, whether appreciable only by the intellect or perceptible by the outward senses; while, on the other hand, he saw, that if he rose up and quitted his native land, deceit would also depart from his mind, changing his false opinions into true belief.

At the same time, also, the divine oracles of God which were imparted to him excited still further that desire which longed to attain to a knowledge of the living God, by which he was guided, and thus went forth with most unhesitating earnestness to the investigation of the one God. And he never desisted from this investigation till he arrived at a more distinct perception, not indeed of his essence, for that is impossible, but of his existence, and of his over-ruling providence as far as it can be allowed to man to attain to such;

for which reason he is the first person who is said to have believed in God, [*]( Genesis xv. 6.) since he was the first who had an unswerving and firm comprehension of him, apprehending that there is one supreme cause, and that he it is which governs the world by his providence, and all the things that are therein. And having attained to a most firm comprehension of the virtues, he acquired at the same time all the other virtues and excellencies also, so that he was looked upon as a king by those who received him, [*]( Genesis xxiii. 6. ) not indeed in respect of his appointments, for he was only a private individual, but in his magnanimity and greatness of soul, inasmuch as he was of a royal spirit.
