The following are agencies that I find worthwhile to follow in ascertaining whats going on with the Church world wide:
Center for the Study of Global Christianity.
U.S. Center for World Missions.
Voices of the Martyrs.
Lausanne World Pulse.
The Christian Telegraph
Rainbows of Hope
I would like to include individual missions organizations in which many of my friends belong, but some of these agencies deal with high security risk regions, so reluctantly, these will not be listed.
Other sites of Interest:
The Center For Early African Christianity
All India Christian Council
Centerpoint International : Focusing on the African nation of Liberia.
Here are some excellent secular resources:
Christian Science Monitor.
Hudson Institutes Center For Religious Freedom
This list shall be periodically updated.
