Yeah no-one can go anywhere near the ice wall hey? You get shot down or intercepted. When Jesus returns this will all be moot. Read this yesterday - And I saw a new heauen, and a new earth: for the first heauen, and the first earth were passed away, and there was no more sea. 2And I Iohn saw the holy City, new Hierusalem comming down from God out of heauen, prepared as a bride adorned for her husband. 3And I heard a great voice out of heauen, saying, Behold, the Tabernacle of God is with men, and he wil dwell with them, and they shall be his people, and God himselfe shalbe with them, and be their God. 4And God shall wipe away all teares from their eyes: and there shall bee no more death, neither sorrow, nor crying, neither shall there bee any more paine: for the former things are passed away. 5And he that sate vpon the throne, said, Behold, I make all things new. And hee said vnto me, Write: for these words are true and faithfull. 6And he said vnto mee, It is done: I am Alpha and Omega, the beginning and the end. I will giue vnto him that is athirst, of the fountaine of the water of life, freely. 7He that ouercommeth, shall inherite all things, and I will bee his God, and he shall be my sonne.
