The jury decides innocence or guilt. In our current sinful world sometimes juries make mistakes; they sometimes set the guilty free and wrongfully convict the innocent.

This heavenly jury will be "packed", hand-picked and completely biased. Nevertheless, it's decisions will be 100% correct, 100% accurate and the defendant will be 100% satisfied with a fair verdict. Why? Because every defendant, as juror will decide his own case, and will know that the decision is correct and just.

How is this possible? Because the truth (everything) will be completely revealed and each defendant will be convicted of that truth and will judge by their own measure. They will be unable to deny the truth revealed to them and unable to declare their own verdict unfair (see When All is Revealed).

For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. Matthew 7:2

For if we would judge ourselves, we should not be judged. But when we are judged, we are chastened of יהוה, that we should not be condemned with the world. 1 Corinthians 11:31-32

Behold, יהוה cometh ... To execute judgment upon all, and to convince [with His words of FIRE] all that are wicked among them of all their wicked deeds which they have wicked committed, and of all their hard speeches which wicked sinners have spoken against him. Jude 14-15

What is the use or purpose or good of convincing the wheat and grapes of their wickedness, if not for their conversion and restoration?

For by FIRE and by his SWORD will יהוה [Yahweh] plead with all flesh: and the slain [literally "pierced" as in a pierced heart or converted] of יהוה shall be many. Isaiah 66:16

I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear. Isaiah 45:23

For it is written, As I live, saith יהוה [Yahweh], every knee shall bow to me, and every tongue shall confess to יהוה. Romans 14:11

... then shall every man have praise of יהוה [Yahweh]. 1 Corinthians 4:5

This is when the lake of fire streaming from the mouth of the judge, will have done its work, ALL will worship the King, every knee shall bow and death will be forever destroyed (thrown into the lake of fire).
