When my son was 4, I was in a Women's Bible Study group. They had classes for children as well, while we studied in our groups. One day, as my son and I were walking to our car, he said to me, "Mom, I'm not going to sin anymore."
You can imagine my pride at hearing this. Then I got to wondering why he said this, so I asked him.
His answer was quick: "Jesus said if you don't sin, you can throw the first stone, and I want to throw the first stone."
Two nuns were driving alone out in a rural area. They ran out of gas. Fortunately they could walk to a gas station not far away, where they asked to purchase a can of gasoline.
"I'm sorry, sister," said the attendant, "but all I have for you to carry it in is an old chamberpot." The nuns agreed that this would be fine.
They returned to the car. As they were pouring the gasoline into the tank, a man drove by, stopped his car, and said, "Oh sister, if only I had your faith."
