An wonderful object lesson with the parable of the good samaritan
Gert van Bos gave me this fun idea:
"Once, to tell the story of the Good Samaritan, I used a specially made cross. Because the story starts with a conversation about the great commandment 'Love the Lord God with all your heart' and the second commandment 'Love your neighbour as yourself’, I got the idea of making a wooden cross with PVC piping running through it. You could make it out of plexiglass instead of wood, but this one is more surprising.
