The Question of Evil with Ravi Zacharias

I got this interaction from many of Ravi's lectures and from his book, Can Man Live Without God (pg. 182).

Ravi Zacharias, a Christian philosopher, had an interesting interaction with a student at the University of Nottingham in England. As soon as he finished one of his lectures, the student shot up from his seat and blurted out, "There is too much evil in this world; therefore, there cannot be a God." Ravi said, "If there is such a thing as evil, aren't you assuming there is such a thing as good?" The student paused, reflected, and said, "I guess so." Ravi countered, "If there is such a thing as good, you must affirm a moral law on the basis of which to differentiate between good and evil. When you you say there is evil, aren't you admitting there is good? When you accept the existence of goodness, you must affirm a moral law on the basis of which to differentiate between good and evil. But when you admit to a moral law, you must posit a moral lawgiver. That, however, is who you are trying to disprove and not prove. For if there is no moral lawgiver, there is no moral law. If there is no moral law, there is no good. If there is no good, there is no evil. What, then, is your question?"

The student responds with, "What, then, am I asking you?" Indeed. What is the question?
