"Eunice Black, a Relief Society teacher, told of a speaker who set out 10 apples to represent his monthly income. He 'paid' one apple for food, two apples for rent, and so on until only one apple remained—a tithing apple. Then he asked the bishop to stand next to him. He said that he hoped the Lord would understand he still had many bills to pay and could pay only part of his tithing that month. Then he took a big bite out of the apple and handed the bishop the partially eaten fruit. This lesson left a powerful impression on Sister Black. She determined to pay tithing first, then budget the remainder of her money."
