Whose judgement seat?

Why do you judge your brother? Or why do you also look down on your brother? For we will all stand before the judgment seat of God; for it is written: ‘As surely as I live,’ says Jehovah, ‘to me every knee will bend, and every tongue will make open acknowledgment to God.

For we must all appear before the judgment seat of the Christ, so that each one may be repaid according to the things he has practiced while in the body, whether good or bad.
