A ward house was in need of painting, but there was no budget to buy paint and pay someone to paint it. The bishop asked a member of the ward who was a painting contractor if he would donate his labor towards the cause. The brother agreed, the paint was purchased and delivered to his home. As the contractor looked at all the paint and imagined the hours it would require for him to complete the church job, he was tempted. He thought to himself that if he thinned the paint some he would be able to have to some paint that he could use in his business which would reimburse him somewhat for all of his effort.
He completed the job Saturday night and thought that all would be well as long as it didn't rain before the paint dried. Alas, he woke up Sunday morning to pouring rain. He went to the meeting house and saw the bishop shaking his head as he watched the paint running from the building. The contractor was humbled and apologetic. The bishop accepted his confession and gave him this advice, "Repaint, repaint! And thin no more."
