Luke became a successful evangelist- pastor working in the River Lake Gospel Tabernacle in Minneapolis, a similar ministry to that of his brother Paul, who was pastor of Chicago Gospel Tabernacle from 1921 to 1933. He was a forceful preacher, particularly interested in prophecy, whose ministry was primarily centered in the Tabernacle rather than in itinerant evangelism, though he did preach occasionally in Chicago at the Gospel Tabernacle. Rader's fine singing voice was a particular asset in his work, which also included a radio ministry. This collection consists of one tape, the first side of which records short radio messages by Rader with anecdotal stories and pithy comments on their biblical significance. The second side of the tape is almost entirely short segments of musical selections, including hymns presumably sung by Rader, though he is not introduced or identified.
Musical accompaniment includes organ, brass ensemble, orchestra, and piano.
Approximately half of the second side is of poor technical quality. This tape was purchased in December 1981 from Resurrection Radio of Minneapolis, Minnesota.
