Unbelievers are going to be judged by the Scriptures on the Last day…

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. (Revelation 20:12)

At the great White Throne judgment depicted in the 20th chapter of the book of Revelations, we are contextually told that all of the unbelievers, both great and small, will be judged according to the contents of multiple books. One of the books that are opened is described as the Lamb’s Book of Life (Revelations 12:15); but the other books are not identified by name.  Nevertheless, I believe that (at least some of) these other books are the same books that comprise the scriptures. Let me show you why:

1) 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. (John 12:48)

If the word that Christ has spoken is going to judge unbelievers on the last day, where else can one find the word’s that Christ has spoken but in scripture?

2) Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip. For if the word spoken by angels was steadfast, and every transgression and disobedience received a just recompense of reward; How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him. (Hebrews 2:1-3)

The Scriptures give at least two reasons why it is impossible to escape (God’s Judgment) if we neglect the great salvation that Christ has secured for us by His death on the cross:
(1) The words spoken by angels are steadfast –  this is a reference to the scriptures, for we are told that these angelic words are also the things which we have heard (in verse 1) and the angelic transmission of God’s words are also confirmed in Act 7:53 and Galatians 3:19.
(2) Every transgression and disobedience will receive a just recompense of reward – in other words – God will judge and reward every sinner according to the sins he/she has committed.

So, during the Judgment, God’s verdict of guilty is inescapable primarily because of the steadfastness of the scriptures; this confirms that the scriptures must play a role during the judgment of the unforgiven. Furthermore, it is interesting to note that Hebrews 2:3 also addresses the other criteria that God uses during the Great White Throne Judgment, namely, God’s promise to judge unbelievers according to their works.  Hebrews 2:3 mentions that for the unbeliever, every transgression and disobedience will receive a corresponding punishment, again, this is a confirmation of the Judgment according to works that is mentioned in Revelations 20:12

3) Do not think that I will accuse you to the Father: there is one that accuseth you, even Moses, in whom ye trust. For had ye believed Moses, ye would have believed me: for he wrote of me. But if ye believe not his writings, how shall ye believe my words?
(John 5:45-47)

Christ equates belief in Moses to belief in the Scriptures (Moses’ writings) and mentions that Moses (specifically his writings) will accuse these unbelievers.
