How does God's forgiveness differ from the parable of the unforgiving servant?

In the parable of the unforgiving servant (Matthew 18:23-35), the king forgives his servant based solely on compassion, without the requirement of justice being met. This is not how God operates. God's forgiveness is perfect; it satisfies both His justice and His mercy. While the king can forgive out of compassion alone, God's forgiveness is based on the sacrificial atonement of Christ, demonstrating that His justice must be satisfied before He extends forgiveness. Thus, while humans may forgive from compassion, God's forgiveness is drawn from His eternal purpose and righteousness, signifying that He never compromises His justice.
