Your brother has been missing for months and there is mounting evidence that he is dead. Is it rational to hope that he is alive and keep searching for him?  

Is it rational to have faith in the existence of God because, if he turns out to exist, your faith may let you into heaven while a lack of faith could condemn you to hell?
