The Kingdom of Heaven

As I watched the film ( the kingdom of heaven) tonight I was once again reminded of the intolerance of the religious finatics. It is a scary thought to know any action can be rationalized and pushed forward by saying that it is gods will. Their is no criteria for approval or any such thing, people in the church simply follow any leader thinking that god has put them in that place of power. Consider this, the church down the street can have drastic differences while "following the same god and same religion". So is eternal life based on the chance of which church is closest to your home or where your friends go or any of the ACTUAL factors that decide where one places their loyalty... Just another fault in the idea of religion
