Christianity - A Process of Transformation

As I have moved about amongst Christians in many parts of this world, and in many situations, one thing has been growing upon me more and more strongly. In the presence of a great deal of confusion amongst Christians and many complications in Christianity, the feeling has become stronger and stronger that the need is for Christians really to know what Christianity is, and to know what it is that they are in as Christians. That sounds, perhaps, rather drastic, but I am quite sure that a very great deal of the trouble - and I think all agree that there is a good deal of trouble in Christianity generally - is due to a failure really to understand what Christianity is...
