Rev 6:10-11 They cried out with a loud voice: “Lord, the one who is holy and true, how long until you judge those who live on the earth and avenge our blood?” (11) So they were each given a white robe, and they were told to rest a little while longer until the number would be completed of their fellow servants and their brothers and sisters, who were going to be killed just as they had been.
They will cry out to the Lord, asking how long it will be before He will avenge them. In reply each is given a white robe and informed that the Tribulation is not over and that others must be martyred before God’s judgment on the wicked and deliverance of the righteous occurs at the Second Coming. This passage shows that the time period is the Great Tribulation, but not its end.
Spirits without any substance could not wear robes. The fact that they will be given robes supports the concept that when believers die they are given temporary bodies in heaven which are later replaced by resurrection bodies at the time of resurrection.
