Depends of the Christian, how they came to the faith, what was their life like, what is their temperment. A fundamentalist probably quotes the KJV bible like law, sees himself as a servant of God and holder of the Faith. An Evangelical probably see herself as here to lead others to the faith. A Born-Again may have been brought up in the faith, left it, found dissatisfaction in the world, ended up on drugs or multiple bad relationships, then found a faith that helped them put their life in order. They probably have a varied approach to life.
The answer, I don't know. As a Buddhist would say, it takes 10000 lifetimes to find the answer.
Depends of the ChristianYes, I suppose so. I am a christian that has the answers to those questions and peace in my life because of it. It is really quite simple, I am a child of God, created to worship and enjoy Him forever. My life has purpose and dignity. I wish that everyone could enter into that kind of contentment.
