I was asked to do exactly that by a member who is fascinated by all the intrigue and gore of the Old Testament stories.
As it happened, the Lectionary threw up the David and Goliath incident, so he was a happy bunny (although he quipped that sick bags should be handed round !!)
I didn’t overdo the violence of the story, rather to allegorise it a little by considering what giants are around today. The physical individuals who make our lives hell, through to the ‘things’ like illness and bereavement.
I author suggested naming the stones we pick to help us defeat our giants, from courage, faith, hope through to friendship, prayer and Scripture.
I had the feeling that there were many aching hearts in the congregation today and that we all needed to think about such things.
Giants can be faced and defeated.
