2 Nephi 25:8

wherefore, they are of worth unto the children of men, and he that supposeth that they are not, unto them will I speak particularly, and confine the words unto mine own people: for I know that they shall be of great worth unto them in the last days; for in that day shall they understand them; wherefore, for their good have I written them.

So these words will help people. If anyone thinks they won’t help, I will speak especially to them. I will keep the words for my own people. I know these words will be very helpful to them in the last days. In that day they will understand them. I have written them for their good.

Isaiah’s words matter. They’re valuable. And to anyone who thinks they’re not, let me speak directly: I’m writing these things for my own people. They’ll be precious to them in the last days, when they finally understand them. That’s why I’ve written them down—for their good.
