Field Team:

Benjamin Muti_Fotor

Ben Mutti

Benjamin Mutti has been involved with a wide array of issues concerning public policy in his hometown of Mansfield, Ohio. His activities involve proposing legislation at the local level to protect families from social ills, and equipping citizens to be good stewards of their communities.

Just recently Ben was a recipient of the 2010 Rosa Parks Citizen Activist Award presented by the Cincinnati based group "Citizens for Community Values," for Ohioans who work and live to uphold family values.

Ben’s work with pastors across denominational lines has provided valuable insight on clergy attitudes towards social issues. His pastor surveys and op-ed articles allow him to perform the duties of a media liaison for Christendom in north central Ohio. His goal of promoting persevering prayer and strategic partnerships has been quite evident through the coordination of several corporate assemblies, the annual National Day of Prayer observance, and various other clergy press conferences.

While working for county government, at heart Ben is a researcher and observer of contemporary transformational revival. Ben now serves The Sentinel Group in a support staff capacity. In short, Ben adheres to the words of the wise sage Ben Franklin who once said, "He who shall introduce into public affairs the principles of primitive Christianity will change the face of the world."
