Here is how the Gospel writer Luke see the life of Christian according to Thomas Cahill in "Desire of the Everlasting Hills". It is a picture of a virtuous cycle between prayer and showing kindness to your neighbor.
Kindness doesn't spring from having a lot of wealth or resources to share. In fact for many, the habit of preserving or even hoarding wealth make them selfish according to Luke's Gospel. Well, this is another perspective and a very old fashioned one on the widening wealth gap isn't it?
Inevitably the divide between the rich and poor will narrow. The question is would it be achieved peacefully or violently. Will we do it ourselves or test God's patience to the point that he intervenes on the side of the disenfranchised.
