What do we do when we know we have made a mistake? David’s pride led to a cataclysmic fall. Plague decimated his people. He prayed for them. God sent Gad the prophet to give him instructions. David built an altar at the threshing floor of Arauna. Then he paid for and made a sacrifice to the Lord that day. Someone will pay for our sins. We can either use the installment plan, or accept the perfect sacrifice of God’s only Son.
