"There is really nothing complicated about the new heavens and the new earth. To aid our understanding of this beautiful truth let us learn a lesson from the symbolisms of the book of Revelation. The key to this understanding is the word “sea.” As soon as John sees the new heaven and the new earth he immediately notes that “there was no more sea.” Again and again throughout the book of Revelation we have shown that the word “sea” is not used in the literal sense of the vast oceans of earth, but in a figurative and symbolic way. The vast majority of the events in the Revelation take place in one of three dimensions: HEAVEN, EARTH, and SEA. These three realms, of course, represent three dimensions of life within each of us, three states of being, life-styles, levels of consciousness, spheres of existence, and realms of experience. There is a “heaven” realm within our spirit, an “earth” realm within our soul, and a “sea” realm within our body. The highest of these realms is heaven — where God dwells in our spirit. Earth is the in-between realm, a dimension that at its highest touches heaven, and at its lowest kisses the sea. That is the soul which lies between the spirit and the body. It can yield to the spirit above to become heavenly, or to the sea (body realm, flesh nature) to become sensual and devilish."
"The lowest of these three realms is the sea. Throughout the scriptures the sea is a type of the inner storms and turbulent nature of the Adamic man. The prophet Isaiah penned these inspired words: “The wicked are like the troubled sea, which cannot rest, whose waters cast up mire and dirt. There is no peace, saith my God, to the wicked” (Isa. 57:20-21). Jude also described wicked men when he said, “These are raging waves of the sea, foaming out their own shame” (Jude 13). No one can dispute the fact that it is this restless, turbulent, raging, evil heart of the fleshly man, with the passions and lusts and the motions of sin that lurk in the body with its lower nature, that inspires every evil and devilish perversion, and has filled the world with ever increasing confusion, faithlessness, immorality, falsehood, fraud, hatred, violence, greed, cruelty, strife, wars, bloodshed, and every wicked work. It is more than a raging sea of evil — it is a virtual tsunami of self-destruction!"

"Consider again these awesome words: “And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away.” How unutterably significant this is! John tells us in the plainest of words that there is a new heaven and a new earth for…that is, because…the former heaven and the former earth had passed away. The message is just this — God cannot bring forth His new until the old has been done away with! If the Spirit of God has begun to build in your life a new world and a new order, and left any of the old citadels of fleshly living, of self-will, of carnal understanding, of religious mentality, and worldly ways and means standing, they would have to come down. You may congratulate yourself upon their remaining, but it is a false congratulation, your glorying is not good. I am sure of this, that Christ will never put a new piece upon an old garment, or new wine in old wineskins: He knows the rent would be worse in the long run, and the bottles would burst. All that is of the flesh’s spinning must be unraveled. The natural building must come down, lath and plaster, stud and truss, roof and foundation, and we must have a house not made with hands, of a new creation."
