Revelation 21:4

God changes things, changes us...helps us..fixes us.

We dont make ourselves better or more worthy of heaven...
God is at work in us....

He will wipe every tear from their eyes.
There will be no more death or mourning or crying or pain, for the old order of things has p***ed away."

the limitations we suffer now because we are yet mortal are taken away.
We will know even as we are known,,,and we will be known for sure.
