XXI. (100) But it is not sufficient for the lover of wisdom to have a hope of good things, and to expect all kinds of admirable things, because of the predictions given to him, but unless he also knows the manner in which he is to arrive at the succession of his inheritance, he thinks it very grievous, inasmuch as he thirsts after knowledge, and has an insatiable desire of attaining to it; on which account he puts a question, saying, "O Lord God, how shall I know that I shall inherit it?" (101) Perhaps some one may say that this question is at variance with perfect faith, for that to feel such a difficulty is the part of one who doubts, but that it is the part of one who believes to seek for nothing further. We must say, therefore, that he both doubts and has believed, but not about the same matter, far from it, for he has believed that he is to be an inheritor of wisdom, but he only seeks to know the manner in which this event will take place; that it really will take place he does by all means confidently comprehend, in accordance with the divine promises. (102) Therefore the teacher having praised the desire for learning which he feels, begins his explanation with the first elementary instruction, in which this is set down as the first and most necessary thing, "Take for Me."[Ge 15:9.] The sentence is brief, but the meaning is great; for there are not a few things implied in these words. (103) In the first place you have, says God, no good thing of your own, but whatever you fancy that you have, another has bestowed it upon you. From which it is inferred that all things are the property of God who gives them, but that they do not belong to the creature which only existed after him, and which stretches forth its hands to take them. (104) In the second place, he says, even if you take them, take them not for yourself, but think what is thus given you a loan or deposit, and be ready to restore it to him who has deposited it with, or contributed it to you, requiting an older favour with a newer one, and an original kindness with one proffered instead of it, as justice and propriety require.
