Most church leadership is not purposely corrupt. Many were never called into leadership by Jesus. Most of us like to be in the majority. The leadership of today again sits in Moses' seat, hindering God's people from entering into the kingdom. In summary then, wolves of the past and wolves of the present use the sheep to build little kingdoms for themselves.
Shepherds serve to the sheep true drink and true meat.
They bring the sheep into the kingdom made up of righteousness, peace, and joy in the Holy Spirit.
