[Cvengr]

There will be loss.
1Co 3:11-15
(11) For other foundation can no man lay than that is laid, which is Jesus Christ.
(12) Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
(13) Every man’s work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man’s work of what sort it is.
(14) If any man’s work abide which he hath built thereupon, he shall receive a reward.
(15) If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.

.
Those verses are applicable only to those that remain technically in covenant, yet whose lives have taken on goals that do not enrich their spiritual being.

It is similar to Yeshua’s parable of the man who built on sand.

There will be loss.

Thanks, but my question was different:

Will there be regret, remorse, or envy for some in heaven?

I think this gets more to the point of your theology. If there is a felt loss then there is regret, remorse or envy - it the loss matters to us this is how.

If there isn't, then it doesn't matter, we are oblivious to it. If it does matter, well, then you have the problem of regret, remorse, or envy in heaven.
