Sometimes it helps to understand something by its opposite.  So consider these two stories about ingratitude.

The Woodman and the Serpent

One wintry day a Woodman was tramping home from his work when he saw something black lying on the snow. When he came closer he saw it was a Serpent to all appearance dead. But he took it up and put it in his bosom to warm while he hurried home. As soon as he got indoors he put the Serpent down on the hearth before the fire. The children watched it and saw it slowly come to life again. Then one of them stooped down to stroke it, but the Serpent raised its head and put out its fangs and was about to sting the child to death. So the Woodman seized his axe, and with one stroke cut the Serpent in two.

“Ah,” said he, “No gratitude from the wicked.”

The Unforgiving Debtor

A Parable from the Gospel of Matthew

Then Jesus said, “The kingdom of God is like a king who decided to square accounts with his servants. As he got under way, one servant was brought before him who had run up a debt of a hundred thousand dollars. He couldn’t pay up, so the king ordered the man, along with his wife, children, and goods, to be auctioned off at the slave market.  The poor wretch threw himself at the king’s feet and begged, ‘Give me a chance and I’ll pay it all back.’ Touched by his plea, the king let him off, erasing the debt.

“The servant was no sooner out of the room when he came upon one of his fellow servants who owed him ten dollars. He seized him by the throat and demanded, ‘Pay up. Now!’

“The poor wretch threw himself down and begged, ‘Give me a chance and I’ll pay it all back.’ But he wouldn’t do it. He had him arrested and put in jail until the debt was paid. When the other servants saw this going on, they were outraged and brought a detailed report to the king.

“The king summoned the man and said, ‘You evil servant! I forgave your entire debt when you begged me for mercy. Shouldn’t you be compelled to be merciful to your fellow servant who asked for mercy?’

The king was furious and put the screws to the man until he paid back his entire debt. And that’s exactly what my Father in heaven is going to do to each one of you who doesn’t forgive unconditionally anyone who asks for mercy.”
