There was a tradesman, a painter called Jock, who was very interested in making a penny everywhere he could. So, he often would thin down paint to make it go a wee bit further. As it happened, he got away with this for some time, but eventually the local Baptist Church decided to do a big restoration job, including painting one of their biggest buildings.
Jock put in a bid and because his price was so low, he got the job. So he set to erecting the trestles and setting up the planks and buying the paint and, yes, I am sorry to say, thinning it down with turpentine. Well, Jock was up on the scaffolding, painting away, the job nearly completed when suddenly there was a horrendous clap of thunder, the sky opened, and the rain poured down. It washed the thinned paint from all over the church and knocked Jock clear off the scaffold to land on the grass among the gravestones of the church’s small graveyard.
There he lay, surrounded by telltale puddles of the thinned and useless paint. Jock was no fool. He knew this was a judgment from the Almighty, so he got on his knees and cried: “Oh, God! Forgive me! What should I do?”
And from the thunder, a mighty voice spoke... (You are going to love this) “Repaint! Repaint! And thin no more.”
