We will be speaking as Father and son, as that is my position via my Elder Brother's sacrifice, and which is also my privilege this side of eternity. The Great White Throne holds no fear for me because perfect love cast out all fear.

I don't see anywhere in Scripture any indication that a man will be capable of uttering the first syllable when standing at judgment. The reference I like is contained in Matthew 22:12 (KJV)
12 And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless.

The foregoing is in the Lord's parable regarding the Marriage Supper of the Lamb. The point is that this man did not wear the robe of righteousness which is only attainable by gift through the Lord Jesus Christ. When asked of God, he found he could not respond.

In Revelation 20, the Great White Throne Judgment is described. God makes it clear that He knows every thought, every nuance, every smirk, and every deed each of us will ever act out. All of this to be revealed at the time of the Judgment. In other words it will be the full revelation of each man's own actions which will speak everything which could possibly be said at the Judgment, as each life will be shown in it's entirety on His Judgment bar big screen.

But in any case no man will speak before Him. The Lord Jesus advocates for us in this time, it is He who will judge us in that. But even if we could speak, and I maintain that we cannot, what could we possibly say to the One Who already knows all?
