I would like to develop this discussion (if that is OK) to ask what type of judgement do we think we should expect as believers when the Lord returns for us. This again is something that is often preached about in rhetorical language, that I wonder what is the reality.If as believers all our sin has been judged and removed in Christ, can there be a replaying of and reminding of past mistakes or failures? Using the example of Elijah, do you think he will be reminded about his running scared from Jezebel? Or how about David, will he continue to feel guilty about his adultery? Or will we all be so taken up with the beauty and majesty of Christ that nothing else will take our attention? No guilt or shame.
Good question and I think it is very much in keeping with the OP. I think of the judgment seat of Christ mentioned in 2Cor.5:10-11;
"For we must all appear before the judgment seat of Christ, that each one may receive the things done in the body, according to what he has done, whether good or bad. 11 Knowing, therefore, the terror of the Lord, we persuade men; but we are well known to God, and I also trust are well known in your consciences."
I take that to refer to the judgment of both believers and unbelievers(I know many Christians believe it only refers to the judgment of believers).
Paul says there that there is a real "terror" to this judgment. But we are not told exactly how that will be played out or applied to believers on that day.
Romans 14:10 also mentions the judgment of believers;
"But why do you judge your brother? Or why do you show contempt for your brother? For we shall all stand before the judgment seat of Christ."
I'm also reminded of 1Cor 3:11-15 which describes different levels of rewards and losses;
"For no other foundation can anyone lay than that which is laid, which is Jesus Christ. 12 Now if anyone builds on this foundation with gold, silver, precious stones, wood, hay, straw, 13 each one's work will become clear; for the Day will declare it, because it will be revealed by fire; and the fire will test each one's work, of what sort it is. 14 If anyone's work which he has built on it endures, he will receive a reward. 15 If anyone's work is burned, he will suffer loss; but he himself will be saved, yet so as through fire."
In verse 15 Paul says that some will "suffer loss" even though they will be saved from eternal damnation. That seems to indicate some kind of sorrow.
My musing is that it's probable that the "sorrow" will only happen at the time of the judgment seat as far as believers are concerned.
That said, I agree that there will be different levels of authority and/or privileges and responsibilities throughout eternity according to certain passages of Scripture.
