God can ordain things to come to pass in judgement, and still have His people speak against the ones commiting outrageous sinful acts.
and here in heaven the saints still cry out to God against their persecutors and killers
So apparently people in heaven have not forgotten how they were treated by the wicked.. while alive on earth.
We see here both the judgement and predetermination of God in the things that He ordains to occur.
9 When He opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony which they held. 10 And they cried with a loud voice, saying, “How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?” 11 Then a white robe was given to each of them; and it was said to them that they should rest a little while longer, until both the number of their fellow servants and their brethren, who would be killed as they were, was completed.
