The Great White Throne Judgement is where those who have rejected Christ's sacrifice for their sins should provide an account for all their deeds on earth.
The Christ Rejecters will get what they rightfully deserve in hell, while believers would enjoy the undeserved favour of God in Heaven. The punishment in hell varies for each person, depending on the intensity of their sinful activities.
11 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.
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 in it, and death and hell delivered up the dead in them: and they were judged every man according to their works.
14 And death and hell were cast into the lake of fire. This is the second death.
15 And whosoever was not found written in the book of life was cast into the lake of fire."
Born-Again believers will not be cast to hell, even though we may not be any better than the unbelievers in terms of our righteousness. Our sins are already paid in full by our Savior Jesus. We have received undeserved grace and favour.
We will stand perfect and faultless before God by wearing Christ's righteousness imputed on us ALONE.
Never forget to thank God every day for such grace bestowed on us!!
