There was a tradesman, a painter called Wayne, who was very interested in making a penny where he could, and he would often  thin down paint to make it go a wee bit further.  As you might expect, he got away with this for some time.

Then one day the big, First Baptist Church decided to do a  restoration job on one of their biggest buildings. Wayne put in a bid for the painting, and  because his price was so low, he got the job.

Soon 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, Wayne was up on the scaffolding, painting away, the job nearly completed
when suddenly there was a horrendous clap of thunder, and the sky opened, the rain poured down.
The rain came down so hard it washed the thinned paint completely off the church building and knocking Wayne clear off the scaffold.  He was dazed for a moment, but when he came to,  he was in the church cemetery.  There he lay,   among the gravestones, and surrounded by telltale puddles of the thinned and useless paint.

Wayne was no fool. He knew this was a judgment from the Almighty, so he got on his knees and cried: "Oh, God! Please forgive me! What should I do?"

And from the thunder, a mighty voice spoke...

"Wayne, Repaint! Repaint!  And go thin no more!"
