Destroyed and Renewed

Then shalt thou delight thyself in the Lord; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the Lord hath spoken it. (Isaiah 58:14)

But they shall sit every man under his vine and under his fig tree; and none shall make them afraid: for the mouth of the Lord of hosts hath spoken it. (Micah 4:4)

Heaven and earth shall pass away, but my words shall not pass away. (Matthew 24:35)

The ultimate reward for obedience to God is eternal life in a restored world, without this hope everything else would be pointless. This hope makes every soul of infinite value, because God can give it the power to live forever and do an infinite number of things. I don't need to understand this to believe it, just like I don't need to understand quantum physics to believe it.
Jehovah promises that our eternal life will not be lived in the clouds playing harps, though we probably could do this if we wanted. It will be lived here on earth, with all the world restored; all the waste cleaned up. Not only will the earth be destroyed and renewed, heaven will also be destroyed and renewed, but the words of Jesus will never be destroyed and renewed because they are untainted.

We can trust that the Bible in our hands is true because Jehovah has preserved it over the centuries.
