Regarding your first activity, the first book of John perfectly matches the outline mentioned in your question, as it's often considered as the handbook of christianity (Jesus 101, if you may).
In relation to your second question, John was known as The Apostle of Love because of the transformation he had endured to become a loving pastor-like mentor in his writings and teachings. This was particularly special because John used to be somewhat reckless, aggressive and impulsive, to then become this humble, loving, compassionate man.
