Great the Debt and Greater the Mercy

Matthew 18:26
"The servant therefore fell down, and worshipped him, saying, Lord, have patience with me, and I will pay thee all."
(Matthew 18:26 KJV)

"Then his master summoned him and said to him, ‘You wicked servant! I forgave you all that debt because you pleaded with me.  And should not you have had mercy on your fellow servant, as I had mercy on you?’"
(Matthew 18:32-33)
