This handwritten sermon dates back to 1977, for the Fourth Sunday in Lent. He refers to a hymn that was written by Martin Luther, containing the title of the sermon in its lyrics.
The Gospel text is from Luke 15, which contains the parable of the prodigal son. As far as I can tell, the lyrics from Luther’s hymn mentioned in this sermon are probably from verse four of Dear Christians, one and all rejoice, if a Google Books search can be believed.
Also, there are two notes at the bottom of the sermon which look like references to the hymns Beneath the Cross of Jesus and Come to Calvary’s Holy Mountain.
