A painter named Jack always tried to save a buck whenever he could, so he often would thin down his paint to make it go a wee bit further. He somehow managed to get away with this for some time.
One day, the local church decided to do a big restoration project. Jack put in a painting bid and because his price was so competitive, he got the job.
He erected the trestles. put up the planks, and started thinning down the paint with turpentine.
As Jack was up on the scaffolding painting away, there was a horrendous clap of thunder. The sky opened and the rain poured down, washing the thin paint from all over the church and knocking Jack off the scaffold to land on the lawn.
Jack was no fool. He knew this was a judgment from the Almighty, so he fell on his knees and cried, “Oh, God! Forgive me! What should I do?”
And from the thunder, a mighty Voice spoke, “Repaint! Repaint! And thin no more!”
