We attempted to get permision from our pastor to move to Kenya, but it didn't work out as well as we wanted it to. It had nothing to do with him, but instead the system he serves. The system is unwielding and exists only to feed itself. I would recommend avoiding all denominational systems, missions agencies, networks, and other groups. At least avoid them in the beginning. Once you are established and know who you are and what you are doing, then you can attempt to benefit from someone's sytem.
