What happens to things that little children hear but do not register?
According to the teaching, what little children hear but do not consciously register does not disappear. It enters the subconscious and remains there until just the right time, then it rises up into the conscience, and they remember it. This shows how deeply heard words can be stored.
Les teaches that people often say little kids won't register what they hear, but he says that is not true. Instead, it goes into the subconscious and just lays there until just the right time, and then boom, it comes up into the conscience, and they remember it. This fits his broader discussion of judging others, hypocrisy, and covert sins, where even mental thoughts make a person guilty. He notes that Jesus extended the commandment against adultery to the heart, so thinking it makes one just as guilty as doing it.
