An advertisement I ran across read: "Now you too can own a Genuine Coin From The Time of Jesus: The Widow's Mite. It's a minor miracle that this coin has survived and now people of faith can study, cherish, and protect it for future generations. It's yet another miracle that they're so affordable."
Then, the ad goes on to quote the Scripture we just heard, "While our limited supplies last, you may order the 2,000 year old Widow's Mite for only $39.95 plus shipping and handling. Remember this is the genuine coin mentioned in the Holy Bible and it makes a perfect gift for your child, grandchild, or favorite clergyman."
The advertisement makes it sound like your buying the actual coin the widow dropped into the receptacle. Of course, you are not. It doesn't exist. Harder still is to purchase the woman's attitude of generosity, which is of greater value in today's market.
