3 Nephi 28:33

And if ye had all the scriptures which gives an account of all the marvellous works of Christ, ye would, according to the words of Christ, know that these things must surely come.—

If you had all the scriptures that tell about all the amazing works of Christ, you would know that these things must happen. You would know this according to the words of Christ.

If you had all the scriptures describing Christ’s marvelous works, you’d know from his own words that these things must happen.
