2 Nephi 2:5

And men are instructed sufficiently, that they know good from evil. And the law is given unto men. And by the law, no flesh is justified; or, by the law, men are cut off. Yea, by the temporal law, they were cut off; and also, by the spiritual law, they perish from that which is good, and become miserable forever.

People are taught enough to know good from evil. The law is given to people. But the law can’t save anyone. The law cuts people off. By the law of this world, they were cut off. And by the law of God, they die and become sad forever.

People have been taught enough to know good from evil. The law was given to humanity. But the law doesn’t make anyone right with God—it cuts them off instead. The earthly law cut them off, and the spiritual law makes them lose everything good and become miserable forever.
