Symbolizing your Faith
Anders displayed a strong belief in his faith by collecting small pennies. The habit further strengthened his belief in God and His goodness. He had a pure motive behind collecting pennies and saw them as a divine gift from God. For Anders, it reminded him that someone was looking after him.
The total sum may not have been much to many other people, but for this man, it was substantial. Saving a penny a day might one day amount to something huge, like around $5k. It also goes to confirm the saying that little drops of rain could make a great river one day.
