I am your shield
This sermon is the second in the series "I am your shield" and is the originating passage for the theme. It is also the first recorded sermon in the series because of extenuating circumstances with the first sermon in the series. This sermon reminds the hearers of the backstory to the Abraham and Sarah story and then helps the congregation to see themselves in this story.
Of interest may be the underlying congregation context of Pastor Laura getting ready to leave the congregation and their need to find a new pastor.
