I was talking with Jenna this morning, and she was pondering on how she can really know wether there is a God or not. And I told her that there are lots of things that we can never really KNOW. How do you know gravity is real? You can test it, but you can't see it. You can only see what it does, and by the nature of its actions we make our best guess. How do you know love? You can only see its effects, you can't really KNOW it, you just believe that someone loves you because of how they act.
"But mummy, I know you love me. No matter what. I can always see it in your eyes."
