A more thorough explanation:

Definition: God's penny is a term used in history to refer to earnest money, which is a small sum of money paid when making a deal or agreement.

For example, in the past, when people wanted to buy something, they would give the seller a small amount of money as a sign of their commitment to the deal. This money was called God's penny because it was seen as a way of showing that the buyer was serious about the agreement and that they were willing to put their trust in God to make sure that everything went smoothly.

The term God's penny comes from the idea that the money was a symbol of the Holy Spirit's presence in the transaction. It was believed that by giving this money, the buyer was inviting God to be a part of the deal and to bless it with success.

Today, the term God's penny is not commonly used, but the practice of giving earnest money is still common in many cultures and industries. For example, when buying a house, a buyer may give a small deposit to show that they are serious about the purchase and to secure the property until the sale is finalized.
