First, Revelations 13:7: "And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations."
Second, Revelations 12:12: "Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down to you, having great wrath, because he knowth that he hath but a short time.
Yes, heaven and earth changed after the resurrection. I believe the whole book has been accomplished. We are now in an age where Christ reigns in those who have been risen with Jesus Christ, the kingdom of heaven is inside of us, and we express it or bring it into this world through faith, word, and dead. We're not waiting for anything.
