Tired of sickness and death

Recently, I have been struck by how so many of my friends are dealing with serious illnesses, cancer, or the loss of loved ones.

I am tired.

And I'm not even the one dealing directly with these situations.

I can hardly wait for heaven.

"He'll wipe every tear from their eyes. Death is gone for good--tears gone, crying gone, pain gone--all the first order of things gone." Rev 21:4 (Msg)

How do people without faith persevere through.....where is their hope?
