• Greenfield Church of Christ is the sponsoring congregation for Mission USA.  This work is a mobile effort within the United States managed by Brother Perry Sexton. Its aim is to evangelize, by personal contact, those 717 counties in the USA without the church and to assist small congregations. 

• Greenfield Church of Christ also is the sponsoring congregation Costa Rican Theological Institute under the direction of Rafael Barrantes.

 Other works in the United states we support include: Roger Jones at Taylor Street Church of Christ, students attending either the Memphis School of Preaching or Bear Valley Bible Institute, a local television program entitled "A Bible Answer", and a internet radio station called The Gospel Radio Network.  We also provide support for the West Tennessee Children's Home.

Outside of the United States we support several works.  One such work is the Four Seas Bible College in Singapore.  We also support Chris Herd that is currently working in New Zealand.  Other efforts in Asia are under the direction of Ted Lingren.  In India, we support Dean Crutchfield.
