5. A spiritual idea (about which few know anything) inflows into those who are in the affection of truth, and inwardly tells them that what they hear or read is true, or is not true. In this idea are those who read the Word in enlightenment from the Lord. To be in enlightenment is nothing else than to be in the perception, and in the consequent internal acknowledgment, that this or that is true. These are they who are called "the taught of Jehovah" (Isa. 54:13; John 6:45); 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 upon their heart will I write it, and they shall teach no more every man his companion, or every man his brother, saying, Know [Cognoscite] Jehovah; for they shall all know Me (Jer. 31:31, 33-34).
