Refusing forgiveness after receiving forgiveness invites judgment.

Matthew 18:32–35

³²Then his lord, after that he had called him, said unto him, O thou wicked servant, I forgave thee all that debt, because thou desiredst me:

³³Shouldest not thou also have had compassion on thy fellowservant, even as I had pity on thee?

³⁴And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due unto him.

³⁵So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses.
