If you think humanity can get itself out of all this mess without divine help, then you're not being hopeful - you're hallucinating.
If a person is fearful, it is a fearful time. If a person is hopeful, it's a hopeful time. If you look at world events one way, fear is reasonable. If you look at the world another way, hope is justified.
Hope is born of participation in hopeful solutions.
I'm better than I used to be. Better than I was yesterday. But hopefully not as good as I'll be tomorrow.
