Richard Hoefler's book, Will Daylight Come?, includes A homey illustration of how sin enslaves and forgiveness frees. A little boy visiting his grandparents was given his first slingshot. He practiced in the woods, but he could never hit his target. As he came back to Grandma's back yard, he spied her pet duck. On an impulse he took aim and let fly. The stone hit, and the duck fell dead.

The boy panicked. Desperately he hid the dead duck in the woodpile, only to look up and see his sister watching. Sally had seen it all, but she said nothing. After lunch that day, Grandma said, "Sally, let's wash the dishes." But Sally said, "Johnny told me he wanted to help in the kitchen today. Didn't you, Johnny?" And she whispered to him, "Remember the duck! So Johnny did the dishes.

Later Grandpa asked if the children wanted to go fishing. Grandma said, "I'm sorry, but I need Sally to help make supper." Sally smiled and said, "That's all taken care of. Johnny wants to do it." Again she whispered, "Remember the duck." Johnny stayed while Sally went fishing.

After several days of Johnny doing both his chores and Sally's, finally he couldn't stand it. He confessed to Grandma that he'd killed the duck. "I know, Johnny," she said, giving him a hug. "I was standing at the window and saw the whole thing. Because I love you, I forgave you. I wondered how long you would let Sally make a slave of you."
