5820. 'Return, buy us a little food' means that the good of truth should be made their own. This is clear from the meaning of 'buying' as making one's own, dealt with in 5397, 5406, 5410, 5426; and from the meaning of 'food' as the good of truth, dealt with in 5410, 5426, 5487, 5582, 5588, 5655. In general spiritual food includes all good, but specifically it is good acquired by means of truth, that is, truth existing in will and action. For by virtue of being willed and acted out that truth becomes good and is called the good of truth. Unless truth becomes good in this manner it is of no use whatever to a person in the next life; for when he enters that life it goes away from him because it does not fit in with what he wills or consequently with what he loves and takes delight in. In the world a person may have learned the truths of faith not so that he may will them and act them out, and in so doing may make them forms of good, but merely so that he may know and teach them with a view to acquiring position and gain. Even though as a result of this he may be reputed in the world to be very learned, those truths are taken away from him in the next life, and he is left with what he really wills, that is, with the life really his own. What he had been like so far as that life was concerned he continues to be; and, surprising though it may be, he turns away from all the truths of faith and refuses to accept them, no matter how firmly he had embraced them previously. The conversion of truths therefore into forms of good through willing them and acting them out, that is, through living according to them, is what making the good of truth their own implies, meant by 'buy us a little food'.
