Choose a reasonably well-known Bible Story. In this exercise the Garden of Gethsemane is the story.
It may be helpful first to see what facts about the story of Jesus in the Garden of Gethsemane you can recall and write down these on a large piece of paper where everybody can see them. It is most important that people don't look up the story but they use your memory; and that they recall just facts, not opinions or interpretations about the story.
Now draw how you visualise the scene in the Garden. If you find this impossible to draw then try to describe the scene in words. The aim is to help you clarify your own visual image of the scene.
Reflect on the experience. It may be helpful at this point to read how the Bible records the scene.
End with a time of silence and reflection.
With the Garden of Gethsemane it can be instructive at the end to compare the accounts in the three ‘Synoptic Gospels’ (Matthew 26:36ff, Mark 14:32ff, Luke 22:39ff) with that in John 18:1ff.
It can be very interesting to visit a place like the National Gallery to see how different artists have seen the scene; or to have a collection of slides/postcards of paintings to look at.
