In his book The Prodigal God, Tim Keller uses the following story to illustrate how experiencing God's grace can transform our life:

The acclaimed foreign film Three Seasons is a series of vignettes about life in postwar Vietnam. One of the stories is about Hai, a cyclo driver (a bicycle rickshaw), and Lan, a beautiful prostitute. Both have deep, unfulfilled desires. Hai is in love with Lan …. Lan lives in grinding poverty and longs to live in the beautiful world where she works, but in which she never spends the night. She hopes that the money she makes by prostitution will be her means of escape, but instead the work brutalizes and enslaves her.

Then Hai enters a cyclo race and wins the top prize. With the money he brings Lan to the hotel. He pays for the night and pays her fee. Then, to everyone's shock, he tells her he just wants to watch her fall asleep. Instead of using his power and wealth to have sex with her, he spends it to purchase a place for her for one night in a normal world, to fulfill her desire to belong. Lan finds such grace deeply troubling at first, thinking that Han has done this to control her. When it becomes apparent that he is using his power to serve rather than use her, it begins to transform her, making it impossible to return to a life of prostitution.

Keller notes that in a similar way Christians are transformed as we accept how Christ served and died for us while we were unworthy of his love. Keller asks: "Why wouldn't you want to offer yourself to someone like this? Selfless love destroys mistrust in our hearts toward God."
