How do the Jehovah's Witnesses explain Isaiah 51:6 with respect to the paradise earth doctrine?
1 “Listen to me, YOU people who are pursuing after righteousness, YOU who are seeking to find Jehovah. Look to the rock from which YOU were hewn out, and to the hollow of the pit from which YOU were dug out. 2 Look to Abraham YOUR father and to Sarah who gradually brought YOU forth with childbirth pains. For he was one when I called him, and I proceeded to bless him and to make him many. 3 For Jehovah will certainly comfort Zion. He will for certain comfort all her devastated places, and he will make her wilderness like E´den and her desert plain like the garden of Jehovah. Exultation and rejoicing themselves will be found in her, thanksgiving and the voice of melody.
4 “Pay attention to me, O my people; and you national group of mine, to me give ear. For from me a law itself will go forth, and my judicial decision I shall cause to repose even as a light to the peoples. 5 My righteousness is near. My salvation will certainly go forth, and my own arms will judge even the peoples. In me the islands themselves will hope, and for my arm they will wait.
6 “Raise YOUR eyes to the heavens themselves, and look at the earth beneath. For the very heavens must be dispersed in fragments just like smoke, and like a garment the earth itself will wear out, and its inhabitants themselves will die like a mere gnat. But as for my salvation, it will prove to be even to time indefinite, and my own righteousness will not be shattered.
7 “Listen to me, YOU the ones knowing righteousness, the people in whose heart is my law. Do not be afraid of the reproach of mortal men, and do not be struck with terror just because of their abusive words. 8 For the moth will eat them up just as if a garment, and the clothes moth will eat them up just as if wool. But as for my righteousness, it will prove to be even to time indefinite, and my salvation to unnumbered generations.”
