Yes, I'd assert that God was sure enough of the outcome to establish it in Revelation through the penman John. He did so in the OT, and the NT will be the same.
I think of it like watching a movie that I have already seen 100s of times (for me, that would be "School of Rock")... From inside the movie, Dewey Finn (the main character) doesn't know what's going to happen to himself... He goes through each event not knowing what the future holds... From outside the movie, and viewing it from "a different dimension", I know all the details of the movie to where I can basically recite every single line of the movie from beginning to end. I know the life story of Dewey Finn from beginning to end. I know he will have hard times right away, take a substitute teaching job in place of the real person who was contacted for the job, teach those school kids about rock and roll (and recruit them to be his band members and crew) after hearing them play in band class... etc. etc. etc>. all the way until they lose "Battle of the Bands", but the crowd chants for them to come back onstage for another song because his band was the crowd favorite. In short, I know from the beginning of the movie that Dewey Finn is going to end up owning his own "School of Rock" music tutoring studio and lead an "after school" program while his life-long friend teaches the beginner's course for the younger kids. I see the end from the beginning; Dewey Finn doesn't...
In the same (or at least in a similar) way, God sees the end from the beginning; You and I don't...
