3. But a common remark is that no one can comprehend spiritual or theological matters because they are supernatural. Spiritual truths however can be comprehended just as well as natural ones; and even if they are not clearly comprehended, still as soon as they are heard it is possible to perceive whether they are true or not. This is especially the case with those whose affection is excited by truths. I have been permitted to know this by much experience. I have been permitted to speak with the uneducated, with the dull-minded, and with the utterly senseless, as also with persons who had been in falsities, and those who had been in evils, all born within the church, and who had heard somewhat about the Lord and about faith and charity; and I have been permitted to tell them certain secrets of wisdom, and they comprehended everything and acknowledged it. At the time however they were in that light of the understanding which every human being possesses; and felt withal the pride of being thought intelligent. All this happened in my interaction with spirits. Many others who were with me were hereby convinced that spiritual things can be comprehended just as well as natural, that is, when they are heard or read. But comprehension by the man himself when thinking from himself is by no means so easy. The reason spiritual things can be comprehended is that in respect to the understanding a man may be uplifted into the light of heaven, in which light none but spiritual things appear, and these are the truths of faith. For the light of heaven is spiritual light.
