Bro. John felt the call to start preaching in the Open-Air in 1993 at the University of Alabama where he attended school. He was a Campus Pastor at the University of Louisiana in Monroe, and at Auburn University where he met his wife Ellen (read their testimony here). In April of 1998, Bro. John and Sis. Ellen answered the call to go full time "into the highways and hedges, and compel them to come in, that my house may be filled" (Luke 14:23). So they stepped out by faith, selling most of their possessions and moving from campus to campus in an RV. During this time they learned a lot (sometimes through trial and error) and experienced God's blessings living totally by faith as the Lord met all of their financial needs, many times through unexplainable and amazing events.  They traveled through 34 states, preached in over 90 different college campuses and 3 foreign countries.

In 2003 Bro. John and Sis. Ellen felt the need to concentrate on a particular university campus in the country. After much prayer, they settled in Athens, GA - home of the Georgia Bulldogs.

Bro. John is also a Cancer Survivor. In 2004 he was diagnosed with B-Cell Lymphoma and went through Chemotherapy and Radiation treatments. This interrupted his ministry on campuses and churches for about a year when his cancer went into remission. During this time the Lord worked in our lives in amazing ways. It was a time of prayer and reflection, study, and much growth.

Bro. John is an ordained minister. He has graduated from Southwest Bible College and Seminary with a Bachelor of Arts in Theology, a Masters of Arts in Theology, and a Doctorate in Theology.  In 2011, Bro. John Duncan accepted the position of Senior Pastor of Faith Tabernacle in Talmo, GA where he presently ministers on a regular basis.

They have no association with other street or open-air preachers. Bro. John and Sis. Ellen attend a local church, submit to local elders, pastors, a district superintendent for the region, and a national general overseer (bishop). These are godly men who personally know them and speak into their lives besides many other friends and pastors who keep them accountable.

Sis. Ellen was born in São Paulo, Brazil, and came to the USA as an exchange student in 1989. It was during her stay with her host family that she came to know Jesus Christ. She graduated from Auburn University in 1997 with a degree of Bachelor of Science in Computer Science. The couple has no children.

Bro. John and Sis. Ellen long to see Jesus Christ presented in a FULL Gospel. They are unashamedly Pentecostal and regularly see the Holy Ghost being manifest in their meetings through His gifts, both inside churches and outside in the streets and in the open-air. They believe that "without holiness, no man shall see the Lord" and do not subscribe to the usual traditions and customs attributed to certain holiness "sects."

"It is not all about the healing and the miracles… It is because of a strong message of repentance and holiness that the signs following are effective in bringing in lost souls." (John Duncan)
