When will the works of the martyred saints of the Tribulation be judged?
There is no judgment of the works of martyred Tribulation saints. It would not be necessary because in the Tribulation there will be no room for carnal, wishy-washy believers. The issues in the Tribulation between Christ and the Antichrist will be so clear cut that those who make a decision for Jesus know they are risking their very lives in doing so and many are martyred. In fact, the Tribulation saints co-reigning with Messiah are those who actually were martyred for their faith. They clearly already evidenced, by their martyrdom, their absolute loyalty to Messiah and, therefore, there is no need for any special evaluating judgment for them.
