In addition to his music, Johnny is a gifted communicator, preacher and mission’s spokesperson. Johnny and his wife, Teri, have three sons and reside in Woodstock GA.


One Voice Mission (Formerly Music Evangelism Foundation, MEF) was founded in Colorado Springs, CO in 1981 as the non-profit ministry of song evangelist Jamall Badry. Being a skilled vocalist and deep lover of Jesus, Jamall had a profound passion for expository preaching and excellence in music.

As a result, in 1981, Jamall launched a week long Bible conference in Colorado Springs that would become the flagship event of MEF/OVM. In time the MEF Word and Worship Conference would become one of the premiere Bible conferences in North America.

 Jamall loved to tell the story of that very first conference in 1981. It was a great leap of faith, but he believed God told him to do it so he booked all the preachers and musicians and spent thousands of dollars. Only 14 people showed.

Discouraged and ready to quit, a woman approached Jamall at the end of the week and said, “Mr. Badry, if what I heard this week is the gospel then I’ve never heard it before. God changed my life and I thank you for doing this if only just for me.”

And Jamall heard the Lord say, “Was it worth it, Jamall…was it worth it for just this ONE?” And “the rest as they say is history”.

And the vision grew. Jamall’s love for music led him to sponsor a series of concerts in Branson MO featuring some of the musicians he loved and showcased at the conferences. The “Down from His Glory” concert series in Branson was the highlight of people from all over the US.

And he didn’t stop there…Jamall had a passion for missions and traveled to Africa and India on many occasions. It was his desire to serve indigenous pastors and church planters to see the gospel go where it was not.

On August 29, 2010, at the age of 75, Jamall was promoted to Glory. But his legacy lives on in the ministry of MEF/OVM. Under the leadership of OVM’s current director, Johnny Hall, the ministry is now in its 41st year and going strong. To God be the Glory.

After many conversations and much consultation, the OVM board and staff decided in 2017 that it was time for a name change. We are continuing the legacy of our founder, but felt our name was not consistent with our overall direction.

As an events based nondenominational ministry, we chose “One Voice Mission” as our title. OVM is faith-based nondenominational ministry. For nearly four decades it has been facilitating events showcasing some of the finest preachers and musicians from around the globe. We are bringing God’s people together as One Voice to encourage one another and to worship Him together.

We are also an organization committed to “finishing the task” of the gospel work as Christ commanded us. Through our One Voice Mission Partners, we are working in support of international indigenous missionaries who are reaching those who have never heard the gospel.

Hebrews 10:24-25 is a fitting text for our ministry: “And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.”


The “Old Singer” OVM/MEF Conference 2010

“The OVM/MEF conference featured messages and music focused on the sovereignty and faithfulness of God. Together we committed ourselves to ministering to all the nations of the world. The OVM/MEF vision continues as the torch is passed to a new generation.”

–Ray Pritchard

“The 2012 Word & Worship Conference was the best ever - better than any conference, revival or holy gathering that we have attended in our lives.”

–Shirley and Elton Gillam

“Singing and ministering with consummate professionals committed to the Lordship of Jesus Christ is a rare experience for those of us in similar ministries. And then to be able to sit under the Bible teaching & exhortations we received..."priceless."

–Soloist Tim Kaufman
