Matthew 18:32-35

32 "The king summoned the man and said, 'You evil servant! I forgave your entire debt when you begged me for mercy.

33 Shouldn't you be compelled to be merciful to your fellow servant who asked for mercy?'

34 The king was furious and put the screws to the man until he paid back his entire debt.

35 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."
