JW's help each other...that's good.
JW's don't typically help anyone outside of their sphere of influence.
Charity, as a Christian, should be showed to anyone who needs it. An organization that helps only its own is not charitable, it's investing!
From the movie, Angels and Demons, "My church feeds the hungry. My church comforts the sick and the dying. What does your church do?" That may well sum up what Christianity is all about...at least in the beginning. No true church exists today that follows that example to the same degree.
