Talking about Christianity outside of church or your groups is difficult, especially if you're talking to a non-Christian. Witnessing shouldn't be as difficult as it seems, and it's not nearly as scary.
Following his previous book, Faith That Sees Through the Culture, Alfonso Espinosa brings witnessing to an easy and accessible level with Faith That Engages the Culture. Using a concept called the Engagement Triangle, you can learn how to witness in today's world to the people that need to hear the Good News the most. Not only does the Engagement Triangle help you to understand how to witness on external topics such as politics or science, but you'll also learn how to witness to internal topics, such as mental illness.
