worry and stress
I just started reading this book called Crazy Love by Francis Chan. It's a great book, I'd recommend it!
Here's a quote:
Worry implies that we don't quite trust that God is big enough, powerful enough, or loving enough to take care of what's happening in our lives.
Stress says that the things we are involved in are important enough to merit our impatience, our lack of grace toward others, or our tight grip of control.
