If you get married as Jacob did, putting the weight of all your deepest hopes and longings on the person you are marrying, you are going to crush him or her with your expectations. It will distort your life and your spouse's life in a hundred ways. No person, not even the best one, can give your soul all it needs. You are going to think you have gone to bed with Rachel, and you will get up and it will always be Leah. This cosmic disappointment and disillusionment is there in all of life, but we especially feel it in the thing upon which we most set our hopes.

Tim Keller, Counterfeit Gods, pg 38-39

Keller is one of the most gifted speakers, taking a Manhattan postmodern society and introducing them to biblical truths and a dynamic relationship with Jesus. He points out is this masterful work, how many things serve as a counterfeit god, when God does not reside as the only king to the throne.

It is a sad state when something so beautiful as a marital partner is a tool to getting filled up. We are all very leaky people, with leaky hearts and leaky love. Some areas cannot be healed with the science of modern medicine. Only when a heavenly love is experienced will a person no longer clamor on another with expectations that are unrealistic.

Being addicted to a human relationship is, as Keller points out, idolatry and a counterfeit god.
