Theodore Epp

Theodore H. Epp (January 27, 1907–October 13, 1985) was an American Christian preacher, radio evangelist, and author, best known as the founding director of Back to the Bible, a globally influential radio ministry. Born in Oraibi, Arizona, to Russian Mennonite immigrant missionaries working with the Hopi Indians, Epp grew up in a faith-filled environment. Converted at age 20 in 1927 under Norman B. Harrison’s teaching in Flagstaff, Arizona, he pursued theological education at Oklahoma Bible Academy, Hesston College in Kansas, and the Bible Institute of Los Angeles (now Biola University), earning a Th.M. from Southwestern Baptist Theological Seminary in Fort Worth, Texas, in 1932. Epp’s preaching career began as a pastor in Goltry, Oklahoma, at Zoar Mennonite Church (1932–1936), where he married Matilda Schmidt in 1930, raising six children—Gerald (who died young), Eleanor, Herbert, Bernice, Marilyn, and Virginia. In 1936, he joined T. Myron Webb’s radio ministry, and on May 1, 1939, launched Back to the Bible in Lincoln, Nebraska, with just $65, trusting God for provision. The program grew from a 15-minute local broadcast to a daily 30-minute show on over 800 stations worldwide in eight languages by his 1985 retirement, featuring his expository preaching and music from the Back to the Bible choir and quartet. He authored nearly 70 books, including David: A Man After the Heart of God and Practical Studies in Revelation, emphasizing practical faith and biblical literacy.

Scriptures
The Renewed Mind
Philippians 4:8,9; 2 Peter 1: 1-9 A good exercise is to analyze the kind of thoughts you have been thinking. Some will be spiritual thoughts that make a positive contribution to life, others will be thoughts about things that are not necessarily good or bad, and there will be thoughts that are definitely bad--and you realize this without anyone's telling you so. The quickest way to deteriorate or to degenerate is to allow your mind to be occupied with unworthy thoughts. We soon become what we think. Thinking good thoughts contributes to building character; thinking bad thoughts leads downward. Jesus explained that the mouth really reveals what is in the heart: "The good man out of the good treasure of his heart brings forth what is good; and the evil man out of the evil treasure brings forth what is evil; for his mouth speaks from that which fills his heart" (Luke 6:45, NASB). What the conscious mind thinks on gradually sinks into the subconscious mind and becomes the building blocks, or material, for one's character. "For as he thinks within himself, so he is" (Prov. 23:7, NASB). We can make a positive contribution to our subconscious mind by controlling the thoughts of our conscious mind. But when we think selfishly, covetously, jealously and lustfully, these characteristics will become evident in our character. "And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect will of God" (Rom. 12:2).
