OC is a faith-based mission who depends on the Lord to provide committed financial supporters and partners for mission giving. The contributions from these individuals help generate ministry opportunities around the world, impact mission workers and their global work, and provide a means for the International Mobilization Center to function. In our commitment to honoring donor intent, if a worker is part of a field team, any remaining support balance at the end of each fiscal year will be given to that team for ongoing ministry to that country or region of the world.

You can be a part of mobilizing church leaders around the world by donating to OC. You can see a summary of the Lord’s blessing on OC’s ministry and finances in our Annual Report.
