Samuel Eugene Ballentine was Associate Professor of Hebrew and Old Testament. The service begins with organ music (00:00-04:00). The speaker delivers the Scripture reading, and he gives a word of prayer (04:01-05:45). The speaker reads from Mark 9:10-29 (05:46-08:10). Ballentine uses the story of the healing of the boy with an unclean spirit to preach on the subject of doubt, and he sounds a plea to the audience to have the courage to doubt in a culture where certainty is prized and encouraged (08:11-21:55).
