These kinds of bible studies like to wallow in the myths of the OT, and extrapolate conduct from those myths.  If the NT is studied, it is only Paul.  Jesus is a concept, not a guide to conduct.  He is invoked, but prayers are to the angry and vengeful god of the OT.  Jesus' teachings are filtered and altered as necessary.  I've been through some of these studies.  They are not christian.  They are their own religion, adopting Jewish myths as fact and supporting conduct abhorrent to the teachings found in the gospel.  Prosperity gospel is a subset of this religion.
