From the work The Apocalypse Explained 242.5

…the faith of knowledges before it becomes the faith of life is historical faith, the nature of which is well known, namely, that it is believed because another has said it; until this has been made man’s own it is an alien thing, or something with ourself belonging to someone else. Historical faith, moreover, is like a belief in things unknown, for it is said that things must be believed though not understood, yea, that they must not be searched into by the understanding; and yet spiritual faith is such that in it truths themselves are seen and are consequently believed. In heaven no one believes any truth unless he sees it or has seen it; for they say, “Who can believe that a thing is so unless he sees it? It may possibly be false.” And only the evil can believe what is false; for the evil from evil see falsities, but the good from good see truths; and as good is from the Lord, so also seeing truth from good is from the Lord. Angels see truths because the light of heaven, in which they are, is Divine truth proceeding from the Lord; all, therefore, even those in the world, who are in that light are able to see truth.
