God knows the beginning from the end and knows every person’s fate before He is born, but he still pleads with every person and allows them to make their own choice – everyone gets a fair chance – Jesus knew that Judas would betray Him, but for the sake of transparency and allowing Judas to see that Jesus had given him every chance possible to redeem himself, Jesus allowed Judas to continue down this path. You see, God could have destroyed Satan after he sinned or even prevented sin from ever entering the universe, but then His creation would never have understood the results of sin and followed him as “robots” – the same with the investigative judgement, God must reveal the lives of the wicked and the righteous, in order to prove that He has judged justly. The books will be opened and there will be complete transparency with regards to the choices that had been made by people on earth and the results thereof.
At 11 minutes it is evident who is doing the judging. God is the ultimate judge of everyone who has ever lived and still alive. This judgement must be done prior to His second coming (as you will see in this video).
