BTTT. VOM has made a great difference in my faith. I had a set of cassette tapes (dark ages ...) from one of their first conferences, and the speakers were very impressive.
I am astounded at the heroism of VOM personnel, and of the persecuted believers they seek to help. We in America are so fortunate (so far). To whom much is given, much is expected; I think we are obligated to help our brothers and sisters in more dangerous environments.
