This sermon is a combination of typing and handwriting in red and black ink. It lists a date, but not a year. Since Advent 2 is listed, we can assume that it was a Sunday, so this sermon was probably preached in 1973 or 1979, since those are two years that 12/9 was on a Sunday.
The Gospel text is listed as Luke 3:1-6, which corresponds to the second week of Advent in year C. There is a hymn listed to follow the sermon, Lord, speak to me, that I may speak 538. I found a recording of the Hymn, and will include it below the sermon.
