God is looking for people to use, and if you can get usable, he will wear you out. The most dangerous prayer you can pray is this: ’Use me.’

In this saying, Warren frames Christian discipleship as availability rather than mere belief: God’s work advances through people who are willing to be “used” in service. “Get usable” suggests cultivating humility, obedience, and readiness—traits that make a person responsive to perceived divine direction. The hyperbole “he will wear you out” underscores the costliness of vocation: sustained service can be exhausting, demanding time, comfort, and personal ambition. Calling “Use me” the “most dangerous prayer” warns that sincere surrender may lead to unexpected assignments and sacrifice. The line functions as motivational exhortation, pushing listeners from passive spirituality toward active, costly ministry.
