In an earlier post, I mention that God will not be happy until he has all of us. This is also true the other way around; that is, we won't be fully happy until we have all of God.
At the beginning, we discover God and our life becomes meaningful. As we get to know God better, we yearn for a more intimate relationship. Eventually, we seek complete union with him in this life. But God is so beautiful that even at full union the yearning for more of him does not stop. Indeed, we and God are made for each other. We'll never be fully content until we get to heaven. I consider this to be our tremendously good fortune.
