Apparently, according to Lily, if you ever try to learn about anything without the aid of a college or university, you could never be an expert in that subject. So even studying it for 70 years is useless without college guidance. (Also, there is nothing in Camping's claims that states that he knows more than Christ. Nor is he claiming he knows more than God, since by thinking that there were hidden messages in the Bible, he's telling us that God is telling us something about the end through the Bible.)
