Men never do evil so completely and cheerfully as when they do it from religious conviction. (Blaise Pascal, 17th century French theologian)
Religious zealots can be dangerous. It isn’t that worship is hazardous; it’s when false doctrines are knowingly taught as truth. Today there seems to be a renewed interest in the “spiritual,” but we must be extremely careful to be sure that our spiritual interests are centered in “true religion.” In part that will be demonstrated by lifestyle, free from evil.
Pure and genuine religion in the sight of God the Father means caring for orphans and widows in their distress and refusing to let the world corrupt you. (James 1:27)
