2 Corinthians 5:1 NLT
“For we know that when this earthly tent we live in is taken down (that is, when we die and leave this earthly body), we will have a house in heaven, an eternal body made for us by God himself and not by human hands. 

Our bodies may be deteriorating but we have a hope, one day we will have a heaven body, a perfect body, no more pain, sickness, suffering or death.
