The Issachar Economic Model (2 CDs) or Free Download
Although the Joseph model of prosperity helped God's people prosper in Egypt for a season, in the end, they all become slaves to the world system of their day. Likewise, the application of Joseph's financial model today works for a time, but everyone still ends up in slavery to the world's system.
God is currently calling His people to come out of the world (Egypt) and take possession of their Promised Land, which requires a different model. Joshua gives God's new financial model to the children of Israel just before they entered the Land, and the sons of Issachar applied it best.
