According to Sam Storms, in his book One Thing (Storms, C. Samuel. One Thing: Developing a Passion for the Beauty of God. Fearn, Ross-Shire, Scotland: Christian Focus, 2004. Print.), we were created for happiness. But we don't always "get" that concept.
"Many Christians today are horribly out of touch with this truth. They aren't resistant to joy, but they're more than a little suspicious of it. The problem is that they are oblivious to the beauty of God. Worse than that, they're bored. God is real to them. They're not atheists. He just isn't relevant. Far less is he cause for celebration. That's why when life is hard and disillusionment sets in, God isn't the first thing to enter their minds (if they think of him at all). Many instinctively turn to whatever will anesthetize their pain or bring a spark to their souls.
The reason for this isn't hard to see. The human soul wasn't created for boredom. We were shaped by God for the excitement that the revelation of his glory induces. We were fashioned for the happiness that the sweetness of Christ's tender mercies alone can impart. That doesn't sound boring to me!" (14)
