Here is a handwritten sermon for the Advent season that was preached early in December of 1978.
This sermon makes several references to the Greek words Chronos and Kairos, so I’m leaving links to Wikipedia definitions of each word. The gospel text is Mark 13:33-37, which corresponds to the First Sunday of Advent in Year B of the Revised Common Lectionary.
