It Is Written
In the mid-1950s Vandeman started work on a series of television programs called "It Is Written", which he planned to air for several weeks in an area as a warmup to an evangelistic program. In spring 1956, "It Is Written" launched its first telecast in black and white—a full-message, Bible study telecast in Washington, D.C. The program later became one of the first religious television programs to air in color. The program's title was based on the Bible verse , "It is written, man shall not live by bread alone, but by every word that proceeds out of the mouth of God."
