Isaiah 51:6 "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."
Psalm 102:25-26 "Long ago you laid the foundations of the earth itself, And the heavens are the work of your hands. 26 They themselves will perish, but you yourself will keep standing; And just like a garment they will all of them wear out. Just like clothing you will replace them, and they will finish their turn."
So is it going to last forever, or will it wear out and perish? You are taking the Scriptures you want to believe, and dismissing the ones that you don't.
As the Watchtower shows, Ps 37 is considered to be a poetic promise that the Jews would retain possession of the promised land.
"Since Psalm 37:29 has been translated "The righteous shall inherit the land, and dwell therein for ever," does it refer simply to Israel's permanently occupying the Promised Land?" Watchtower 1986 Jan 1 p.31
