God showed Noah a rainbow as a covenant never to destroy the earth by flood again, so I'm always hopeful when I see a rainbow.
Then, this morning, I'm sitting at my desk and I just happened to look up and there on my office ceiling was a rainbow! I don't have any crystals or sun catchers on my windows so I can't imagine what the sun was reflecting off to make such a beautiful rainbow. Maybe some CDs on the floor?
Either way, it's a hopeful symbol.
