2432. This was also made known to me by innumerable experiences, that the persuasions of spirits with cupidity, which I supposed to be salutary and the best, were changed, after some moments, hours [or] days into contrary persuasions; so that hence I knew for certain, that the Lord alone rules the thoughts of man, his prudence and counsels, and that faith should be placed in him, but not in self, and as this is the truth, no doubt should be entertained; just as when ocular truth is given, although we do not know causes, yet we believe, and though explorers do not discover the causes, still we believe, because they see. Now I have seen, heard, felt, [and] known this to be an indubitable truth - wherefore it should not be argued about, as is usual, because I do not know, whether it is a spirit, whether it be so [and so] because I do not understand; but because the thing is so in truth we should believe it sooner than sensuals because the Lord also has said it. - 1748, June 28.
