Human beings have a deep need for fulfillment. It's how God made us. But things go horribly wrong when we seek satisfaction in earthly things. We end up becoming dependent on, maybe even addicted to, things that cannot satisfy us. But if we will seek our fulfillment in God Himself, we'll find that He can do what nothing else can. That’s why seeking fulfillment in God is one of the key lessons on the road to freedom.
