This book aims to guide "How to defend Christianity" and "How to say" in our daily encounters and conversations. The questions' how to defend Christianity and evangelize?' remain a challenging task in our daily encounters and communications for many Christians alike. There is no methodological approach to 'how' in this area. It's not because of a lack of biblical knowledge or learning. Instead, we don't have a model for conversations and don't know the specific communication skills or methods of evangelism, i.e., when, how, and what to say. The discovery of Jesus's dialogue breaks down the barriers between faith and reality and quenches our long-standing thirst and questions about our daily encounters and conversation at once.

The Gospel of John contains a relatively large number of detailed conversations with Jesus. The talks in various situations teach us what to say and convey evangel as a golden rule. I tried to sort it out on my own.

Jesus's conversation tells us what attitude we should take and how we speak. It also introduces an aggressive conversational form that leads to dialogues. In particular, it is gratifying to discover that there is a specific frame in Jesus's dialogue evangelism method. This book introduces it and also contains the way to use field materials and their effective means of conveying the truth in daily life, and introduces the way, how to cope with the frictions /assaults that Jesus had shown.
