Why Do We Need to Defend the Faith?

Most christians to day are ware of the need and importance of defending the faith. Ours is a secular, global and pluralistic world - this is not a christian world. We don't have a general impression that people are aware of the significance of this subject. It's true that through a good deal of western history, christianity was its stage center. But we just have to do a little work with the current situation and we can get back to that pleasant atmosphere that we know really prevails anyway.
