And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.

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.

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.

And death and hell were cast into the lake of fire. This is the second death.

And whosoever was not found written in the book of life was cast into the lake of fire.  Revelation 20:11-15

The Great White Throne Judgment recorded here is for unbelievers.  Unbelief is the only sin that cannot be forgiven because unbelief is a rejection of God’s provision for all our sins.  All other sins can be forgiven.

I believe that blasphemy against the Holy Spirit (the unforgivable sin) and unbelief are one and the same.  No man can come unto God unless he is drawn by Him.  To reject the Spirit’s drawing and conviction is to deny Christ, Christ’s death, burial and resurrection and God’s Word of which the Holy Spirit is the author.  Unbelief denies the truth of the Gospel which makes God a liar.

…..let God be true and every man a liar…..Romans 3:4
