Focus on the 10/40 Window
The Isaiah Group aims to help provide support for evangelism efforts with a focus on the 10/40 window. We aim to specifically support the underground church using whatever means available, whether it be via satellite, printed material, or training of foreign nationals as pastors or missionaries.
