I see and hear this phrase alot during the holidays... Just Believe.
There is something so child-like and wonderful about those two words. I think in our hearts, we do want to just believe -- which might be why so many of us love movies like Polar Express. We want to believe there is something bigger than us. Powerful. Good.
Our hearts tell us, too. We can hear its echos cry "There is more!" Its longing makes us restless. It makes us go searching. Searching until it finds the One that can satisfy it.
Much like the children's book, "Are You My Mother?". The baby bird searched and searched until he found his parent. Not just anyone would suffice, of course. And, he didn't stop until his heart found what it was that it was truly looking for.
