5. There is a spiritual idea of which few people have any knowledge, which flows into those who are in the affection of truth, and which interiorly pronounces that what they hear or read is true or not. This idea is present with those who read the Word in enlightenment from the Lord: and to be in enlightenment is nothing else than to be in the perception and consequently in the internal acknowledgment that this or that is true. Those who are in this enlightenment are they who are said to be taught of Jehovah, Isaiah liv 13; John vi 45; and of whom it is said in Jeremiah:
Behold, the days come . . . that I will make a new covenant . . . This shall be the covenant ... I will put my law in their inward parts, and write it in their hearts ... And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me. Jer. xxxi 31, 33, 34.
