"Truly the Lord is speaking in symbolic language of great spiritual realities fulfilled within His people!"
"Nevertheless we, according to His promise, look for new heavens and a new earth, wherein dwelleth righteousness. Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of Him in peace, without spot, and blameless" (II Pet. 3:13-14). It will be a wonderful day when all the Lord’s people understand the great truth that there is even now a new heaven and a new earth wherein dwelleth righteousness. "We look for it!" Peter says. Since you are looking for it — now give diligence to be found in Him in peace, without spot, and blameless. In other words — BECOME WHAT YOU ARE LOOKING FOR! When you are at peace, without spot, and blameless, you have then discovered within yourself the new heavens and the new earth…the ones wherein dwelleth righteousness! "We look for it!" Peter says. Since you are looking for it — now give diligence to be found in Him in peace, without spot, and blameless. In other words — BECOME WHAT YOU ARE LOOKING FOR! When you are at peace, without spot, and blameless, you have then discovered within yourself the new heavens and the new earth…the ones wherein dwelleth righteousness! This new heaven is the heaven of our regenerated spirit wherein God dwells, and this new earth is the earth of our transformed mind and soul by which we are able to demonstrate through our body in our everyday living, what is that good and acceptable and perfect will of God. Oh, yes!"
"If ye know that He is righteous, ye know that everyone that doeth righteousness is born of Him. Little children, let no man deceive you: he that doeth righteousness is righteous, even as He is righteous" (I Jn. 2:29; 3:7). Can any doubt it — there is the NEW EARTH wherein dwelleth righteousness! Paul speaks the same truth this way, "For the law of the spirit of life in Christ Jesus hath made me free from the law of sin and death. For what the law could not do, in that it was weak through the flesh, God sending His own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: that the righteousness of the law might be FULFILLED IN US, WHO WALK NOT AFTER THE FLESH, BUT AFTER THE SPIRIT" (Rom. 8:2-4). It is the law of the spirit of life in Christ Jesus that makes us free from the law of sin and death. That is the new administration of the new heavens and the new earth!"

"Here we have the two heavens and the two earths — the OLD and the NEW! With astonished wonder the Seer or Patmos beheld this scene in spirit and cried out, "And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away…" It is significant to note that the word translated "first" is the Greek word protos which is rendered in verse four of the same chapter as "the former things," and that is a more accurate rendering. "…for the former heaven and the former earth were passed away." You will understand a great mystery when you see how it is that whatever has ruled or does rule your life apart from the spirit becomes your "former heaven."
