We are made in the image of God. And we have an inbuilt longing to connect with God. Nothing that is transitory can ever fill this need. To fail to connect with God is to fail to be completely human. Nothing that is not God can ever hope to take the place of God. And yet because of the fallenness of human nature, there is a natural tendency to try to make other things to fulfill this need. Created things are substituted for God, and they do not satisfy.
