All in Profession of Faith

The world is comprised of approximately 6.9 billion people, and of those, 2.2 billion are Christian, or to simplify this a bit... over 30% of all the people in the world are Christian. This is an amazing statistic, especially if you listen to the press on the subject. However, the press corps is not the only detractor or naysayer when it comes to the state of the Church... Christians also preach the demise of the Church from the pulpit. Why is this so? Why are we so self deprecating?
