Christians can recognize errors in reasoning by learning to ask questions, analyze, and engage. Mary Jo Sharp offers four questions to ask in almost any conversation: (1) What do you mean by that? (2) How do you know that? (3) Why do you believe that? (4) What is your source? Sharp challenges Christians to analyze what we see and hear and not just be passive receptors. We should be critical but not allow feelings to get in the way. Mary Jo illustrates several examples of logical fallacies using commercials and TV shows explaining how to avoid making the same mistake reasoning.
