When last really isn't last?

John 12:48
48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.

When is this last day that these folks are going to be judged?

Revelation 20:12-13
12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.

So what is this promise of being raised up on the last day referring to if it is not referring to the last day when all the dead are raised and judged according to their works?

John 6:40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.

John 11:24 Martha saith unto him, I know that he shall rise again in the resurrection at the last day.
