Mack Lyon (1921-2015) was born in Muskogee, Oklahoma. Mack committed his life to preaching the gospel at age 14 and preached his first sermon three years later on a Sunday night, November 2, 1939 while still in high school. In those more than sixty-two years, he has lived and worked with local churches in Oklahoma, Arizona, Texas and New Jersey. He was a missionary in Western Australia in the 1960s where he established a congregation in the Riverton suburb of Perth.
Mack Lyon began the IN SEARCH OF THE LORD'S WAY television program in September 1980 on one small TV station in Oklahoma. He has been recognized for his work in religious broadcasting by Freed-Hardeman University in Henderson, TN and by Oklahoma Christian University in Oklahoma City. He has been called a "Pace-Setter" among churches of Christ by the CHRISTIAN CHRONICLE, an international newspaper of churches of Christ. At the end of the 20th Century he was named by THE GOSPEL ADVOCATE, a privately published monthly magazine, as one of 100 "Trail Blazers" of the century among churches of Christ.
