5) Humor shows courage
St. Lawrence showed his courage to his torturers during his martyrdom by saying, "I'm done on this side." It was both a pointed challenge to his executioners and a bold profession of faith. Similarly, in the 16th century St. Thomas more, the onetime chancellor of England who had refused to accede to King Henry's requests to recognize the king's divorce, was sentenced to death. As he climbed the steps to his beheading, he said to his executioner, "See me safe up; for in my coming down I can shift for myself." This type of wit shows profound courage and conveys deep theological truth. It says, "I do not fear death," and "I believe in God." It points to something beyond this world. It is a kind of prophetic humor.
6) Humor deepens our relationship with God
One of the best ways of thinking about a relationship with God is a close, personal relationship or an intimate friendship. In that light, our relationship to God - like any relationship - can use humor from time to time. It's okay to be playful with God and accept the idea that God may want to be playful with us.
In Jewish tradition, there is the notion of a playful or loving God. Many rabbis tell the story of God braiding Eve's hair in the garden, like someone who would help a bride. This is a charming and playful image of a loving God.
