A Sunday school teacher is trying to deliver a lesson to her class of small children. At one of the tables sits Mary, who is drawing a picture. "Mary, what are you doing?"

"Drawing," Mary replies without looking up.

A few minutes go by and the teacher asks again, "Mary, what are you doing?"

"Drawing," says Mary.

"Yes, but what are you drawing?"

"It's a picture of God," Mary says, still hard at work.

"Mary. That's not possible. Nobody has ever seen the face of God," the teacher admonishes.

"They will when I'm finished," Mary replies.
