The phrase kai eidon (I saw) is used throughout Revelation to indicate chronological progression (cf. 6:1, 2, 5, 8, 12; 7:2; 8:2, 13; 9:1; 10:1; 13:1, 11; 14:1, 6, 14; 15:1; 16:13; 17:3; 19:11, 17, 19; 20:1, 4, 11). It has introduced each of the climactic events beginning with the return of the Lord Jesus Christ in 19:11. As chapter 21 opens, all the sinners of all the ages, as well as Satan and his demons, have been sentenced to the lake of fire (20:10â15). With all ungodly men and angels banished forever and the present universe destroyed (20:11), God will create a new realm for the redeemed and the holy angels to dwell in forever.The phrase a new heaven and a new earth derives from two passages in Isaiah. In Isaiah 65:17 God declared, âFor behold, I create new heavens and a new earth; and the former things will not be remembered or come to mind.â In Isaiah 66:22 He added, â âFor just as the new heavens and the new earth which I make will endure before Me,â declares the Lord, âso your offspring and your name will endure.â â What Isaiah predicted is now a reality in Johnâs vision. . . .
