Well-good thing the book of Revelation was a vision to John that had alot of symbolic representations instead of "literal" meanings- notice,keeping things in context with the rest of the bible:
Isaiah 57:20-But the wicked are like the sea that is being tossed, when it is unable to calm down, the waters of which keep tossing up seaweed and mire.
James 1:5-6- 5 So, if any one of YOU is lacking in wisdom, let him keep on asking God, for he gives generously to all and without reproaching; and it will be given him. 6 But let him keep on asking in faith, not doubting at all, for he who doubts is like a wave of the sea driven by the wind and blown about.
Eccl.1:4-A generation is going, and a generation is coming; but the earth is standing even to time indefinite
Psalms 104:5- 5 He has founded the earth upon its established places;It will not be made to totter to time indefinite, or forever
No worries for the earth nor the seas, but the masses of people alienated from God, would be no more,nor satan and his demons that use to reside in heaven-
2peter 3:11-13- 11Since all these things are thus to be dissolved, what sort of persons ought YOU to be in holy acts of conduct and deeds of godly devotion, 12 awaiting and keeping close in mind the presence of the day of Jehovah, through which [the] heavens being on fire will be dissolved and [the] elements being intensely hot will melt! 13 But there are new heavens and a new earth that we are awaiting according to his promise, and in these righteousness is to dwell.
