The entire religion looks exactly as it would if no supreme interventionist being was behind it. It is obviously just another religion created by primitive man to explain the universe we inhabit.
If you take the broad view and look at everything that calls itself Christianity, you cannot really see the hand of God in shaping this thing. It is fractured into more sects and denominations than I could name, bits of it more or less wage war on other bits of it. Looking back across the history of the religion, there are a great many unpleasant and certainly ungodly things there. That's the broad view.
But if you take the narrow view and look at individual people and groups of people, the opposite is true. Here you often see the hand of God at work. Prayers are answered, people are healed, people are transformed, worship works, amazing things happen.
Why is this?
