The Seventh Trumpet is a judgment but not of condemnation. But it's a serious event.

.......................There will be those who labored for Christ with wrong motives, and their works will be found as hay, wood and stubble. These will be burned by the revealing fires of judgment and their rewards will be lost.
...................They are saved, "yet so as by fire".

The labors of others will be found as "gold, silver, precious stones"; and they will receive a full reward.
