J. Warner Wallace gives the following reasons for why so many Christians lose their faith in college: (1) poorly prepared students, (2) aggressive, antagonistic campuses (3) innately fallen human students. The key to lasting commitment is an understanding of truth. Truth can be illustrated as a house, with objective truth residing on the first floor and opinion residing on the second floor. Wallace defines and explains the difference between objective and subjective truth. He also exposes some of the lies told about truth in today's culture and underscores what makes truth true.
