I have two. I'll post one now, and if there's need for it, the other later.
A pastor had spent a lot of time and effort trying to raise money to repaint the church's exterior. However, by the time the drives, bake sales, and donations came, the money wasn't enough to even coat the church once. The assistant pastor, a shrewd man, came to the pastor and said, "Pastor, I know this is God's house, but we only have a limited amount of paint. Why don't we pour a little water into the paint, just enough to spread it out and cover the church. It's white, and the wood underneath is a light wood, no one should notice.
The pastor agreed, and men volunteered. They thinned the paint out with water once, but it was soon apparent it would not be enough. And so they added more water. Still, they were nearly short, and the assistant pastor added even more water, until finally they could cover the whole church.
No sooner were they finished than a storm cloud burst over the church, drenching it ans washing all the paint away. The pastor was devastated. Suddenly, a voice from the sky, deep and resonating, called out to the men.
"Repaint, repaint, and thin no more!"
