I Believe in the Sun Despite Darkness

We all do. Every person I know believes in the sun even when it is dark outside. Why is this? When we lay down at night, we have no guarantee that the sun will be shining the next morning. We do not know that it will be there to greet us when we arise. Yet we believe it will be. Even when we cannot see it, we believe that it is there.

Now you might say you believe because science has proven that there is a sun and that it is not going anywhere. We will keep turning and the sun will stay at the center and tomorrow morning, whether or not we can see it, the sun will be there. But what about the people who lived before we had all this scientific equipment or the ability to fly into space? They too believed the sun would rise the next day. Maybe they couldn't explain why or how but they believed that it would be there. Why? Because it had proven faithful to be there every other day they had been alive. And every day their parents had been alive. And their grandparents and great-grandparents and so on and so forth. Is this proof? Or is it faith? And now that we have proof and maps and galaxies, does it cease to be faith?

What if the sun didn't come up tomorrow? Would you still believe that it is there? Would you need proof? What if the sun was there but we couldn't see its light, for whatever reason? What if we lived in darkness? Would you still believe in the sun? Would you have faith of its return? Or would you need proof? What if everything the scientists told us was wrong? Would you still believe in the sun, despite the surrounding darkness?

Why is it so easy to believe in the sun even when it is dark and so hard to believe in God when we don't see Him?
