All religions need to get the house in order Rob. If they stopped stashing the valuables (they can't take with them to God by the way!!), and used the money to help the poor, the life for millions would improve. However, it pays to keep them poor, as they are the strongest believers always looking for something better. Hence GDP being a good marker of each countries statistical number of believers.

There are plenty of Prophecies that were given in the Old Testimont that have already come true especially about Jesus
Statistically, I'm surprised that over a period of 2000 years they haven't all come true at some point in that period. They probably have, but then it depends on each faiths way of deciphering them.

you have highlighted a huge gulf between the "Believers" and the "non-Believers".
You missed out those in the middle as well, may as well cover all the bases eh?
