When you say a situation or a person is hopeless, you are slamming the door in the face of God.

From John 16:32-33:  “The hour is coming, indeed it has come, when you will be scattered, each one to his home, and you will leave me alone. Yet I am not alone because the Father is with me.  I have said this to you, so that in me you may have peace.  In the world you face persecution.  But take courage; I have conquered the world!”
