Dr. Zacharias rightly points out that the most important question shared by theists and atheists is the one of how we should live. In this talk, Zacharias presents a solid case for why atheists have no acceptable answer for this all-important question. Pursuing the question from the angles of philosophy, the arts, and morality, Zacharias provides an illuminating discussion about the importance of this question and the consequences for failing to answer it adequately, while arguing that Christianity presents a satisfying answer.
