" But,” says he again, “if God much stronger, much might as the wicked devil, why God no kill the devil, so make him no more do wicked?” I was strangely surprised at this question; and, after all, though I was now an old man, yet I was but a young doctor, and ill qualified for a casuist or a solver of difficulties; and at first I could not tell what to say; so I pretended not to hear him, and asked him what he said; but he was too earnest for an answer to forget his question, so that he repeated it in the very same broken words as above. By this time I had recovered myself a little, and I said, “God will at last punish him severely; he is reserved for the judgment, and is to be cast into the bottomless pit, to dwell with everlasting fire.” This did not satisfy Friday; but he returns upon me, repeating my words, “‘Reserve at last!’ me no understand—but why not kill the devil now; not kill great ago?” “You may as well ask me,” said I, “why God does not kill you or me, when we do wicked things here that offend Him—we are preserved to repent and be pardoned.” "
