Gods word promises a new earth( that is-Gods kingdom rule in full control) Not a new planet. Gods word assures that at Har-mageddon. True believers( the other sheep=the great crowd) will be brought through on earth Matt 24:22-Prov 2:21-22) Yes the kingdom is established in heaven, now. It comes to the earth with full control post Har-mageddon. Jesus rules for 1000 years, Turning earth into a Paradise( Eden) All inhabitants lovers of God, All motives of them ruled by love, not profit or stature. One human family. And when all is back to perfection-Jesus hands back the kingdom to his God and Father and subjects himself forever( 1Cor 15:24-28)
Few believe facts-- God( ancient of days) appointed Jesus as his king(Daniel 7:13-15) God is king of eternity, if Jesus were God he would have been king allready). God will NEVER be in subjection to anyone.
So no revelation is not history. The words have not been fullfilled yet. Rev 21:1--- Not here yet--satan is still in control of the majority. That is why this system is getting sicker and sicker. Its fully corrupted except for the Few who have found the road leading off into life.
When your church preaches against education, you are being abused an subjugated.
